Question

If a particle is moving on a circular path of radius r, then distance travelled by the

particle in one-fourth cycle is :

​

Answer 1

Explanation:

distance travelled by a particle for 1 revolution = 2 īī r

¼ revolution = ¼ × 2 īī r = ½ īī r

so the distance travelled by a particle in one-fourth cycle is ½ īī r
