Question

1. A man weighs 700 N on earth. What is his mass? (g = 10 m/s2). On the moon, his weight is found to be 140 N. What is the acceleration due to gravity on the moon? (2)​

Answer 1

Answer:

Since The acceleration due to gravity on the moon is [ 1/6 ] th that of the earth

Explanation:

As the Acceleration due to gravity (g) On moon is 1/6 th of earth so according to the books it Is 1.63 m/s² On moon

TO FIND MASS ON EARTH ACCORDING TO THE ABOVE QUESTION

FORMULA FOR WEIGHT = MASS × (g)

g = ACCELERATION DUE TO GRAVITY

SO MASS = WEIGHT/ g

MASS = 700 / 10 m/s²

THEREFORE MASS = 70 kg
