Question

A particle is moving in a circular path of radius r. The magnitude of displacement of the particle after covering a 1/4th of the circle is
(1 Point)

Answer 1

Answer:

Explanation:

- Since the particle has travelled 1/4 of the circle; ⇒ Its start and end point forms a right angled triangle with 2 sides equal to r and we have to find the hypotenuse 'd'. - Hence, the magnitude of displacement of the particle is r√2.21-May-2020
