Answer 1

Answer:

Explanation:

Hello buddy!

As after “n” rotation.

It will be on the same point as it started so displacement is 0 and according to law it will be 0.

Thanks!

Answer 2

Answer:

zero and zero.

Explanation:

According to the question, we are asked to find the work done in circular motion in a circular path and elliptical path.

We know, in both cases displacement by that particle is zero as it again comes to that point where it started in the first place.

And we also know that,

Work done = Force × displacement

Since displacement = 0

Hence Work done = 0

So we can say as displacement is zero so work done is zero in both circular abd elliptical path.
