Question

A girl is carrying a school bag of 3 kg mass on her
back and moves 200 m on a levelled road. The
work done against the gravitational force will be
(1) 6x103J
(2) 6J
(3) 0.6J
(4) zero​

Answer 1

Answer:

The amount of work done is expressed in the equation: workdone=force×distance. In this case, the total work done is zero as the displacement is perpendicular to the applied force.
