Question

A body moves through a distance of 70 cm and in doing so, does a work of 420J. Find the magnitude of force acting on the body
Plz Help me​

Answer 1

Answer: 600 N

Explanation:

We know that, w=-F.x

here w=420 J, x=70 cm=70/100 m=0.7 m

from the magnitude of w=F.x

we get, 420=F*0.7

or, F=420/0.7=4200/7=600 N
