In the figure shown, a particle `P` strikes the inclined smooth plane horizontally and rebounds vertically. If the angle `theta` is `60^(@)` then the coefficient of restitution is:

A

`(1)/(sqrt3)`

B

`(2)/(sqrt3)`

C

`(1)/(3)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Aong tangent
`u cos theta = v sin theta` …(i)

Along normal
`e = (v cos theta)/(u sin theta) = cot^(2) theta = cot^(2) 60 = (1)/(3)`
