What happens to the work done if the displacement becomes zero despite a force being applied?
RRB JE
20/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:CThe work done is zero.
In a parallel circuit, the current entering the junction equals the sum of currents through the branches, according to Kirchhoff's current law.
22
If a convex mirror forms a point-sized image at its focus, where is the object located?
RRB JE
19/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:AAt infinity
For a convex mirror, rays parallel to the principal axis appear to come from the focus behind the mirror. Thus, an object at infinity forms a highly diminished image at the focus.
23
A scientist wants to demonstrate that dispersion depends on wavelength. She shines monochromatic red light through a prism. What does she observe and why?
RRB JE
19/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:AOnly a single red ray emerges; no spectrum forms because there is only one wavelength
Red light is monochromatic, meaning it has essentially one wavelength. A prism may deviate it but cannot split it into a spectrum of different colours.
24
During a round-trip journey where a person walks to a location at 5 km/h and returns at 3 km/h, which statement about average speed is correct?
RRB JE
20/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:CAverage speed will be less than the arithmetic mean of 5 km/h and 3 km/h.
Average speed = total distance ÷ total time. Because the outward and return speeds are different, the average speed is not the simple average of 5 and 3 km/h.
25
A physicist uses a convex lens to focus sunlight onto a piece of paper and notices the smallest, brightest spot forms at a certain distance from the lens. Which property of the lens does this experiment help to determine?
RRB JE
19/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:DThe experiment helps to determine the focal length of the lens.
A convex lens converges parallel rays of sunlight at its principal focus. The distance between the optical centre and this point is the focal length, so the experiment measures focal length.
26
A student observes that a compass needle deflects when brought near a current- carrying wire. Using your understanding of magnetic fields, explain why this happens.
RRB JE
19/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:AA current-carrying wire creates a magnetic field that exerts a force on the compass needle.
A current-carrying conductor produces a magnetic field around it. This magnetic field exerts a torque on a nearby compass needle and makes it deflect.
27
Which rule helps to determine the direction of force acting on a current-carrying conductor in a magnetic field?
RRB JE
20/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:CFleming's left-hand rule
A current-carrying conductor placed in a magnetic field experiences a force. Fleming's left-hand rule is used to determine the direction of this force.
28
When a gun is fired, it recoils backward as the bullet moves forward. How does this demonstrate Newton’s third law of motion?
RRB JE
19/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:DThe gun pushes the bullet forward, and the bullet pushes the gun backward with an equal and opposite force.
Newton's third law states that every action has an equal and opposite reaction. The gun pushes the bullet forward and the bullet exerts an equal opposite force on the gun, causing recoil.
29
An electric iron uses a heating element made of an alloy instead of pure metal. Which property of alloys justifies this choice?
RRB JE
19/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:AAlloys have higher resistivity and do not oxidise readily at high temperatures
Heating elements need high resistance so that electrical energy is converted efficiently into heat. Suitable alloys also withstand high temperatures without oxidising rapidly.
30
A room heater and an electric bulb both convert electrical energy to heat, but why does only the bulb emit significant visible light?
An incandescent bulb has a filament heated to a very high temperature, so it emits visible light as well as heat. A room heater is designed mainly to transfer electrical energy as heat.
