Question

. A particle completes 1.5 revolutions in a circular path of radius 2 cm. The angular displacement of the particle will be -(in radian)

Answer 1

We know,

Angular displacement in one complete revolution= 2*pi radian

We have 1.5 revolution which means one complete revolution and a half revolution.

We need to find the angular displacement in half revolution first.

Angular displacement in half revolution= angular displacement in one revolution/2

So,

Angular displacement in half revolution= 2*pi/2= pi radian

So,

The angular displacement of the particle in 1.5 revolution= 2*pi + pi= 3*pi

Therefore, the angular displacement of the particle will be 3*pi radian.

Answer 2

Answer:

3 pi

Explanation:

1revolution ......2 pi

so for half revolution....pi

by adding both we get 1.5 revolution so (2+1) pi

3 pi
