Answered by yuvraj0041

wd =0 because the motion is perpendicular

Ishita05: How ?Please elaborate.

Ishita05: (Who gives force and what gets displaced and in which direction?)

yuvraj0041: moon is revolving around earth due to centripidal force which is perpendicular so it will be 0

Answered by NoorSalman

the work done will be zero
as moon is perpendicular to the earth because earth attracts towards their own inside the centre. so, w.d= mgcos90°= mg. 0=O

Ishita05: Work done by whom? Earth or moon .Since,earth exerts force...

NoorSalman: earth
