An. 50 kg​

Answer 1

Earth exert gravitational force on the feet of man

Answer 2

Actually, there are two forces exerting on the man, one being the downward gravitational force and the other the upward supporting force by the earth surface. However, they cancel out.

So man’s is exerting force on earth is 60kg and earth is exerting force on man is 10kg
So 60-10=50kg
