Q. |
A person can jump higher on the moon's surface than on the earth because – |
A. | the moon's surface is rough |
B. | the acceleration due to gravity in moon is smaller than that on the earth. |
C. | the moon is cooler than earth |
D. | the moon has no atmosphere |
Answer» B. the acceleration due to gravity in moon is smaller than that on the earth. | |
Explanation: The acceleration due to the gravitational field of moon (g' = 1.62631 ms-2) is one-sixth of the acceleration due to gravity on the Earth. So the weight of the same body is also 1/6th on moon in comparison to that on the surface of the earth. It is due to this reason; a man can jump six times higher on moon than on earth. |
