Question

2. A particle completes 1.5 revolutions in a circular path of radius 2 cm. Find the angular displacement of the particle.​

Answer 1

Explanation:

It is very simple..

It can be done by unitary method!

We know, 

1 revolution  =   2π radians

So,  10 radian  =   1/2π×10

                          =     5/π Radian
