91
Acceleration due to gravity is maximum at:
RRB ALP (Stage-II)
23/01/2019 / Shift II
2019
✓ Answer:AThe poles
Among these locations, effective gravity is greatest at the poles.
92
A planet's mass and radius are each one-third of Earth's. What is its surface gravity?
RRB Group-D
19/09/2018 / Shift II
2018
✓ Answer:D3g
g'/g = (1/3)/(1/3)² = 3.
93
An object weighs 6000 N on Earth. What is its weight on the Moon?
The Moon's gravity is about one-sixth of Earth's, giving 10 N.
98
Two eggs are dropped from the same height, one onto a hard floor and one onto a pillow. Which is not the expected outcome?
RRB Group-D
05/11/2018 / Shift III
2018
✓ Answer:BBoth eggs break
The intended answer is B: cushioning increases stopping time and reduces average force. Whether an egg actually breaks also depends on height and cushioning.
99
For a given mass in a uniform gravitational field, what does the work done by gravity depend on?
RRB Group-D
22/10/2018 / Shift I
2018
✓ Answer:ADifference between the initial and final vertical heights
W = mg(h_initial - h_final). The duplicate wording of options B and C is retained from the source.
100
Which is not a chemical reaction?
RRB NTPC (Stage-I)
07/04/2016 / Shift II
2016
✓ Answer:CGravity
Gravity is a physical interaction, not a chemical reaction.
