Physics Questions for RRB Group D: Download Free PDF & Practice Now

Are you preparing for a government job in Indian Railways? The RRB Group D exam is a big opportunity, but competition is very high. To clear this exam, General Science, especially Physics, plays an important role. Many students fear Physics because of formulas and numericals, but there is no need to worry. The Physics questions in RRB Group D are very simple and based only on Class 9 and 10 NCERT. Most questions are from daily life examples. If your basics are clear, you can score very well. To help you, we have created a free Physics PDF with important questions. Download it now and start revising easily.

Why is Physics Important for RRB Group D?

In the General Science section (25 questions), physics carries a lot of weightage.

• Maximum Questions: Out of 25 Science questions, you can expect 9 to 11 questions from Physics alone.
• Concept-Based: Unlike Biology, where you memorize names, Physics is about logic. Once you understand the concept (like Newton’s Laws), you can solve any question on it.
• Simple Numericals: The numerical problems are formula-based (like F = ma). They are easy marks if you know the formula.

We have prepared a comprehensive PDF containing exam-level questions. We have chosen questions that cover the unique mix of Light, Electricity, Motion, and Units that RRB Group D is famous for. Download it, save it, and practice these questions to build your confidence.

Q1. What is the SI unit of Electric Current?

(a) Volt

(b) Watt

(c) Ampere

(d) Joule

Answer: (c) Ampere

(Logic: Ampere measures current. Volt is for Potential Difference, Watt is for Power, and Joule is for Energy/Work.)

Q2. When a bus starts suddenly, the passengers are pushed back. This is an example of:

(a) Newton’s First Law

(b) Newton’s Second Law

(c) Newton’s Third Law

(d) Conservation of Momentum

Answer: (a) Newton’s First Law

(Logic: Also known as the Law of Inertia. The body wants to stay at rest, but the bus moves, so the body falls back.)

Q3. Sound waves cannot travel through:

(a) Water

(b) Steel

(c) Air

(d) Vacuum

Answer: (d) Vacuum

(Logic: Sound is a mechanical wave and needs a medium (solid, liquid, or gas) to travel. It cannot travel in empty space.)

Q4. The mirror used by dentists to see large images of teeth is:

(a) Convex Mirror

(b) Concave Mirror

(c) Plane Mirror

(d) Cylindrical Mirror

Answer: (b) Concave Mirror

(Logic: Concave mirrors magnify the image when the object is placed close to it. Convex mirrors are used in car rear-view mirrors.)

Q5. An object of mass 10 kg is moving with an acceleration of 5 m/s^2. The force acting on it is:

(a) 50 N

(b) 2 N

(c) 15 N

(d) 5 N

Answer: (a) 50 N

(Logic: Formula F = m x a. Here, 10 x 5 = 50 Newton.)

Q6. Which phenomenon is responsible for the twinkling of stars?

(a) Reflection

(b) Dispersion

(c) Atmospheric Refraction

(d) Total Internal Reflection

Answer: (c) Atmospheric Refraction

(Logic: As starlight passes through different layers of Earth’s atmosphere, it bends continuously, making the star appear to twinkle.)

Q7. What is the commercial unit of Electrical Energy?

(a) Watt

(b) Kilowatt-hour (kWh)

(c) Joule

(d) Volt

Answer: (b) Kilowatt-hour (kWh)

(Logic: Your electricity bill comes in ‘Units’. 1 Unit = 1 kWh. Watt is the unit of Power, but kWh is the unit of Energy consumed.)

Q8. The fuse wire used in household circuits has:

(a) High melting point

(b) Low melting point

(c) High conductivity

(d) Low resistance

Answer: (b) Low melting point

(Logic: A fuse is a safety device. It must melt quickly and break the circuit if the current gets too high to prevent fire.)

Q9. Which instrument is used to measure Atmospheric Pressure?

(a) Thermometer

(b) Barometer

(c) Voltmeter

(d) Seismograph

Answer: (b) Barometer

(Logic: Barometer measures pressure. Thermometer measures temperature. Seismograph measures earthquakes.)

Q10. If the distance between two objects is doubled, the Gravitational Force between them becomes:

(a) Double

(b) Four times

(c) One-fourth

(d) Half

Answer: (c) One-fourth

(Logic: Gravity is inversely proportional to the square of the distance (1/r^2). If r becomes 2r, force becomes (1/2)² = 1/4.)

5 Preparation Tips to Master Physics for RRB Group D

Physics can be tricky if you just read it like a story. You need a strategy. Here are 5 practical tips to help you conquer this subject:

1. Memorize SI Units: Railway exams love asking about units. Make a chart of units like Power (Watt), Force (Newton), Frequency (Hertz), and Resistance (Ohm). Read it every morning.

2. Focus on “Light” & “Electricity”: These two chapters carry the highest weightage. Understand the difference between Concave/Convex mirrors and lenses. Learn Ohm’s Law (V=IR) by heart.

3. Don’t Fear Numericals: You don’t need to solve IIT-level problems. Group D only asks for direct formula application. Practice 10 basic numericals on F=ma, W=mg, and P=VI.

4. Understand Examples: RRB asks application-based questions. Instead of just memorizing “Newton’s Third Law,” remember the example: Recoil of a gun or Launching of a Rocket.

5. Attempt Topic Tests: Just reading the questions will not help you boost your preparation. Along with that, you must take tests. For that, you can attempt our free topic tests to see if you can recall the right concept under time pressure.
