A cyclist moves from a certain point P and goes round a circle of radius a and reaches Q, exactly at the other side of the point P as shown in figure. The displacement of the cyclist would be

A

`pi a `

B

`2 pi a `

C

`2a `

D

`2pi//a`

Text Solution

Verified by Experts

The correct Answer is:
C

Displacement of the cyclist = Shortest distance between P and Q = PO+ OQ = a + a = 2a
