✓ Answer:BKinetic energy depends on the square of speed, not just on power supplied.
A convex lens forms a real, inverted and diminished image when the object is placed beyond 2F. Therefore, a smaller image of the tree indicates that the tree is beyond twice the focal length.

A device operates at 2 amperes current and 220 volts potential difference for 5 hours. How much electrical energy does it consume, expressed in kilowatt hours (kWh)?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:A2.2 kWh
Power = 500 W = 0.5 kW. Energy used in 30 days = 0.5 × 6 × 30 = 90 kWh. At ₹4 per unit, the cost is ₹360.
73
How do rays parallel to the principal axis behave after reflection from a convex mirror?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:BThey appear to diverge from a point on the principal axis.
The SI base unit of length is metre (m), which is the standard unit used to measure distance and displacement.
74
Why do gases exert pressure on the walls of the container?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:BGas particles move randomly and strike the walls
Gas molecules are in continuous random motion and repeatedly collide with the container walls. These collisions exert force on the walls and produce pressure.
75
Which of the following situations is NOT an example of action and reaction forces?

✓ Answer:CA ball thrown upward comes back down due to the pull of gravity.
Force is the product of mass and acceleration, F = ma. Its SI unit is newton, N = kg·m/s².
76
An object is placed on a shelf 2 m above the ground. If the shelf is raised to 4 m, what happens to the potential energy of the object?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:AThe potential energy doubles
Gravitational potential energy is PE = mgh. If height increases from 2 m to 4 m while mass and g remain constant, the potential energy doubles.
77
A car suddenly changes direction while moving at constant speed. Which aspect of inertia is being demonstrated, and how does the car’s mass influence this effect?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DThe inertia of direction is demonstrated, and a car with greater mass will resist the change in direction more.
Electric current is the rate of flow of electric charge, I = Q/t. Therefore its SI unit is ampere.
78
A ball initially at rest is dropped from a height and takes 5 seconds to reach the ground. What is the average speed during its fall? (g = 10 m/s²)
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:D25 m/s
For an object dropped from rest, v = gt = 10 × 5 = 50 m/s. Average speed during uniform acceleration from rest is (u + v)/2 = (0 + 50)/2 = 25 m/s.
79
If the current in a wire is 2 amperes, how much charge flows through a cross-section in 5 seconds?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:B10 coulombs
Work is the product of force and displacement in the direction of the force, W = Fs cosθ. Its SI unit is joule.

When a light ray enters a rectangular glass slab obliquely from air, what happens to its direction at the first interface?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:CIt bends towards the normal
Atmospheric refraction continuously changes the path of starlight through layers of air with different densities, producing the apparent twinkling of stars.
