Question

Work done by gravitational force in a closd path is zero?

Answer 1

yes..as they r perpendicular to each other and makes 90°

Answer 2

HELLO DEAR USER!

___________________
Work done in a closed path is zero because in closed path initial and final pointsbare same

So

Displacement is shortest possible distance between two points

As final and initial points are same in closed path so displacement is zero

Work is given by

W= Fd

d= 0

W= F × 0

W = 0

So work done by gravitational force in a closed path is zero
