Question

The value of 'g' on the moon is1/6th the value of earth. If the person weights 14 N on surface of moon the weight of person on the earth's surface is________ A 96 N B 84 N C 62 N D 54 N

Answer 1

ANSWER:

option B (84N) is correct

Explanation:

since the value of 'g' (gravity) on earth is approximately 9.8N, the value of 'g' of the moon would be,

1/6 X 9.8

= 9.8/6 N

so, similarly

if a person exerts a force of 14N on the moon,

then let the force exerted on earth be x,

x/6 = 14

x = 14 X 6

x = 84 N
