✓ 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.

✓ 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.
63
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?

✓ 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.
64
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.
Parallel rays falling on a convex mirror are reflected so that they appear to originate from the principal focus behind the mirror.
65
If atmospheric refraction did not occur, which change would be most noticeable during the observation of stars from Earth?
RRB JE
20/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DStars would not twinkle; their light would remain steady.
Action and reaction forces always act on two different bodies. The gravitational force acting on an upward-thrown ball is not paired with another force acting on the same ball as an action-reaction pair.
66
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.
67
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.
68
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.
69
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.
