Which of the following is an example of membrane bound little structures present in a cell?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:BLysosome
The question describes membrane-bound structures found inside a cell, i.e. cell organelles. This is a Biology concept rather than a Physics concept, so it is placed under Miscellaneous within this Physics list.
62
If an ammeter reading increases when a thicker wire replaces a thinner one of the same material and length, what is the most likely reason?
RRB JE
19/02/2026 / 9:00 AM - 10:30 AM
2026
✓ Answer:DThe resistance of the thicker wire is lower, allowing more current
Resistance is R = ρL/A. For the same material and length, increasing the cross-sectional area decreases resistance. Hence a thicker wire has lower resistance.
63
A ball at rest is dropped from the top of a 20 m high building. Calculate the speed with which it hits the ground. (Take g = 10 m/s²)
RRB JE
19/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:D20 m/s
A concave mirror has its reflecting surface curved inward, toward the centre of curvature.
64
A security mirror in a store is required to provide a wide field of view and always form diminished, upright images regardless of the position of objects. Which type of mirror and principle should be used for its design?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:DConvex mirror using the mirror formula for virtual, diminished images
A convex mirror always forms a virtual, erect and diminished image and provides a wide field of view, making it suitable as a security mirror.
65
If a constant force acts on two objects of different masses, which statement best describes their acceleration according to the second law of motion?
RRB JE
19/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:DThe object with smaller mass will have greater acceleration.
From F = ma, acceleration is inversely proportional to mass for a fixed force. Therefore, the smaller-mass object has greater acceleration.
66
Which type of spherical mirror has its reflecting surface curved inwards, facing towards the centre of the sphere?
RRB JE
19/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:DConcave mirror
Gravitational potential energy is PE = mgh. When an object falls, its gravitational potential energy decreases and is converted mainly into kinetic energy.
67
Which of the following does NOT define the motion of a pendulum swinging back and forth?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:CThe pendulum exhibits uniform motion
A pendulum moving back and forth performs oscillatory motion. Its speed and direction change, so it is not uniform straight-line motion.
68
A solar cooker uses a mirror to concentrate sunlight onto a vessel. Which type of mirror is used and what property makes it suitable?
RRB JE
19/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:BA concave mirror because it focuses parallel sunlight to a single point
A concave mirror converges parallel sunlight rays to its focus. Concentrating sunlight at one point produces intense heat, which is why it is useful in a solar cooker.
69
A ball is placed at the edge of a table and left undisturbed. Which form of energy does the ball primarily possess due to its position, and what can happen if it is pushed off the table?
RRB JE
19/02/2026 / 4:30 PM - 6:00 PM
2026
✓ Answer:CThe ball possesses potential energy and will convert it to kinetic energy as it falls.
During a phase change such as melting, supplied heat is used as latent heat to change the state rather than increase temperature. Therefore temperature remains constant until the phase change is complete.
70
What role does the earth wire play in the safety of domestic appliances with metallic bodies?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:DIt provides a low-resistance path for leakage current
The earth wire provides a low-resistance path for fault current to flow safely into the ground, reducing the risk of electric shock.
