STANDARD Physics Acceleration due to Gravity MCQ Question
Type: MCQ-numerical-Medium-Class 11
The length of a seconds pendulum on the surfaced earth is 1 m. Its length on the surface of the moon is
A
1/6 m
B
1 m
C
1/36 m
D
36 m
Correct Answer
Option A
Detailed Explanation
The time period of a seconds pendulum is 2 s. On Earth, L = 1 m and g = gₑ. On the Moon, the acceleration due to gravity is gₑ/6, so the length L' = L/6 = 1/6 m.
