The amount of work done by centripetal force on the object moving in a circular path is

Text Solution

Verified by Experts

Given `vecr_1=2veci+3vecj`
`vecr_2=3veci+2vecj`
so, displacement vector is given by
`vecr=vecr_2-vecr_1` ltbr `=(3veci+2vecj)-(2veci+vecj)`
`=veci-vecj`
Again `vecF=5veci+5vecj`
So, work doe `=vecF.vecS=5xx1+5(-1)=0`
