Question

An object of mass 10 kg is moving in a circular path of radius 2 m . What is the work done on the object ?

Answer 1

hey mate!

work done by the object =0

because path is circular so displacement =0

work done = force X displacement cos theta

also,

velocity vector is perpendicular to the circumference

theta = 90degree.
cos theta =0

so work done =0

Answer 2

Answer:

0

Explanation:

Work = Force x Displacement cos theta

but as it is a circular path displacement will be zero

as theta = 90

cos theta = 0

force acting = 0 so,

0 x 0 = 0
