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.
82
When using the sign convention for spherical mirrors, which direction along the principal axis is considered positive?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:ATo the right of the origin (along + x-axis)
Most solids expand when heated because increased thermal energy causes their particles to vibrate more strongly and their average separation to increase.
83
A passenger in a moving car feels a jerk backward when the car suddenly starts. How does the first law of motion explain this experience?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:AThe passenger tends to remain at rest while the car moves forward, showing inertia.
A concave lens diverges incident rays, spreading the light over a wider region. It can therefore be used to spread light from a small source.
84
What is the sign of the focal length for a convex lens as per the sign convention for spherical lenses?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DPositive
When light passes from a rarer medium to a denser medium obliquely, its speed decreases and the ray bends towards the normal.
85
An electric refrigerator has a power rating of 500 W and is used for 6 hours each day. If the cost of electrical energy is ₹4.00 per kilowatt-hour, what will be the total cost of operating the refrigerator for 30 days?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:A₹360
Potential energy PE = mgh. If mass is reduced to half while height and g stay constant, potential energy also becomes half.
86
A student uses a convex lens to project an image of a tree onto a wall. If the image is found to be smaller than the tree, what can be inferred about the tree's position relative to the lens?
RRB JE
25/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:BThe tree is placed beyond twice the focal length (beyond 2F) of the lens.
Newton's first law describes inertia: an object continues in its state of rest or uniform motion unless acted upon by an external unbalanced force.
87
Which material can be magnetised using the strong magnetic field inside a solenoid?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:ASoft iron
A dentist uses a concave mirror because, with the tooth between the pole and focus, it produces a virtual, erect and magnified image.
88
A wire of a given material has length l and cross-sectional area A , and its resistance is 9 Ω. Another wire of the same material has length l/3 and cross-sectional area 3A. What will be the resistance of the second wire?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:D1 Ω
Kinetic energy is 1/2 mv². For equal masses, doubling the speed makes kinetic energy four times as large. Thus kinetic energy depends strongly on speed.
89
Which statement accurately describes how energy transforms during the free fall of an object under gravity?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DPotential energy decreases while kinetic energy increases, maintaining constant total mechanical energy.

RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DStars would not twinkle; their light would remain steady.
