In a smooth circular tube of radius `R` , a particle of mass `m` moving with speed `V_(0)` hits another particle of mass `3 m` at rest as shown. The time after which the next collision takes place (assume elastic collision)

`pi R/v_(0)`

`2 pi R/v_(0)`

`pi R/2v_(0)`

`pi R/4v_(0)`

Text Solution

Verified by Experts

The correct Answer is:

`(2)`

Relative velocity of separation = Relative velocity approch = `v_(0)`
