Question

A boy having a mass of 60kg holds in hands a school bag of weight 40N. With what force the floor will
push up on his feet? (9 = 10m/s)
1) 100 N
2) 600 N
3) 640 N
4) 64 N​

Answer 1

Explanation:

Acceleration due to gravity on the moon is 1/6 times as that on the earth and we know that mass is property of the material it always remains same and weight is measure of gravitational force, hence

mass of object on moon is 60kg and weight =60g/6=10×10=100N
