Question

Hlw guys plzz give answer...​

Answer 1

$\huge \bold{hlo \: mate}$

The work done is zero as the bodies are perpendicular. so cos 90=0

Therefore work done will be zero .

_________________________________

we know that satellite of the earth is moving in a fixed circular path and when a body moves in circular path and force acting toward its centre i.e. centripetal force and the direction of movement is prependicular so, there is no work done .

⇒ w = Fs cos theta

= Fs*

= Fs* 90°

= 0 ( answer is zero therefore there is no work done )

Answer 2

No work is done because the satellite moves itself due to centripetal force and gravitational force
