What is the gravity of moon as compared to the Earth
A. 1/4 th of Earth
B. 1/5 th of Earth
C. 1/6 th of Earth
D. 1/8 th of Earth
Answer: Option C
Solution(By Examveda Team)
The Moon's surface gravity is about 1/6th as powerful or about 1.6 meters per second. The Moon's surface gravity is weaker because it is far less massive than Earth. A body's surface gravity is proportional to its mass, but inversely proportional to the square of its radius.This Question Belongs to General Knowledge >> Physics
