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.

✓ Answer:AMove away from the shore
The man pushes the boat in the opposite direction as he walks towards the shore, so the boat moves away. A shift is not provided or is cropped in the supplied scan; the available date is retained.

✓ Answer:A−0.50 m/s
V = −mv/M = −0.01 × 250/5 = −0.50 m/s. A shift is not provided or is cropped in the supplied scan; the available date is retained.
84
A trolley starts from rest with acceleration 2 m/s². What is its velocity after 4 s?
RRB JE
14/12/2014
2014
✓ Answer:A8 m/s
v = u + at = 0 + 2 × 4 = 8 m/s. A shift is not provided or is cropped in the supplied scan; the available date is retained.
85
What happens to gravitational force when the mass of one of two objects is doubled, with separation unchanged?
RRB JE
25/05/2019 / Shift I
2019
✓ Answer:AIt doubles
The force is directly proportional to each mass, so it doubles.
86
If the Sun and Earth have masses M and m and separation r, what is the work done by the Sun's gravity during one complete revolution of Earth?
RRB JE
14/12/2014 / Green paper
2014
✓ Answer:AZero
Gravity is conservative, so its net work over a complete closed orbit is zero.
87
The weight of a body at Earth's centre is:
RRB JE
14/12/2014 / Set-2, Red Paper
2014
✓ Answer:AZero
The net gravitational field at the centre of a symmetric Earth is zero, so W = mg = 0.
88
An object is thrown vertically upward with initial speed u. What maximum height h does it reach?
RRB JE
14/12/2014 / Yellow paper
2014
✓ Answer:Au²/(2g)
At the top v = 0. From v² = u² - 2gh, h = u²/(2g).
89
A bullet is fired vertically upward at 196 m/s. What maximum height does it reach? Take g = 9.8 m/s².
RRB JE
14/12/2014 / Red Paper
2014
✓ Answer:A1960 m
h = u²/(2g) = 196²/19.6 = 1960 m, neglecting air resistance.
90
How is gravitational acceleration represented?
RRB JE
23/05/2019 / Shift IV
2019
✓ Answer:BLowercase English letter g
Lowercase g denotes acceleration due to gravity; uppercase G denotes the universal gravitational constant.
