A designer wants to create a device that spreads light from a small bulb to illuminate a wide area uniformly. Which lens should be used and why?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DA concave lens, because it diverges light rays outward
A moving vehicle tends to continue in its original direction when its direction is suddenly changed. This is inertia of direction, and greater mass means greater inertia.
92
A train moves 120 km at 60 km/h and then another 60 km at 30 km/h. What is the average speed for the entire journey?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:B45 km/h
Electric charge is Q = It. For I = 2 A and t = 5 s, Q = 2 × 5 = 10 C.
93
What happens to the potential energy of an object if its mass is halved while its height above the ground remains constant?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DThe potential energy is halved
Using the Cartesian convention for the stated mirror diagram, the sign of a distance depends on its direction relative to the pole and principal axis. The correct option follows from that convention.
94
A dentist uses a mirror to obtain a large image of a patient’s tooth. Which mirror should the dentist use and why?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:BConcave mirror, because it gives a magnified image
For a convex lens, the principal focus lies on the side opposite the incident light. Under the Cartesian sign convention this focal length is positive.
95
A cyclist increases her speed from 6 m/s to 12 m/s in 3 seconds on a straight road. What is her acceleration during this period?
A student claims that two cars of equal mass, one moving at 40 km/h and another at 80 km/h, have the same kinetic energy if their engines provide the same power. What is the error in this reasoning?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ 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.
97
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.
98
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.
99
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.
100
Which of the following situations is NOT an example of action and reaction forces?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:CA ball thrown upward comes back down due to the pull of gravity.
