What is the symbol of the universal gravitational constant?
RRB Group-D
10/10/2018 / Shift II
2018
✓ Answer:BG
Capital G denotes the universal gravitational constant; lowercase g denotes gravitational acceleration.
72
Which natural phenomenon is caused by gravitational interaction between the Moon and Earth?
RRB Technicians Grade-III
29/12/2024 / Shift III
2024
✓ Answer:DTides
Differences in the Moon's gravitational attraction across Earth contribute to tides.
73
Assertion (A): Trees grow against gravity. Reason (R): Nature defines gravitational law. Select the most appropriate option.
RRB NTPC (Stage-I)
20/01/2021 / Shift I
2021
✓ Answer:BA is true but R is false
The source selects B. Shoots generally grow against gravity through negative gravitropism. The reason is vaguely worded and does not explain this growth response.
74
A person jumps 1.5 m high on Earth. How high could the person jump on the Moon with the same takeoff speed, where g is one-sixth of Earth's?
RRB ALP & Technician
13/08/2018 / Shift I
2018
✓ Answer:B9 m
h = u²/(2g), so reducing g by six increases height sixfold: 6 × 1.5 = 9 m.
75
A planet has half Earth's radius and half Earth's mass. What is its surface gravity?
RRB Group-D
12/11/2018 / Shift II
2018
✓ Answer:C19.6 m/s²
g' = g(1/2)/(1/2)² = 2g = 19.6 m/s².
76
A person has a mass of 60 kg on Earth. What is the person's mass on the Moon?
