Question

A man of mass 50 kg carries a bag of weight
40 N on his shoulder. The force with which the floor pushes up his feet will be
(1) 882 N
(2) 530 N
(3) 90 N
(4) 600 N​

Answer 1

Answer:530N

Explanation:

Here mass of man is 50 kg

Therefore weight is mg

Let us take g =9.8 m/s2

Therefore weight =50*9.8=490N

Now weight of bad=40N

Therefore net force =490+40=530N

Now accordingly to 3rd law of Newton action force=reaction force

There fore the force with which the floor will push him up will be also 530N
