A continuous stream of particles, of mass `m` and velocity `r`, is emitted from a source at a rate of `n` per second. The particles travel along a straight line, collide with a body of mass `M` and get embedded in the body. If the mass `M` was originally at rest, its velocity when it has received `N` particles will be

A

`(mvn)/(Nm+n)`

B

`(mvN)/(Nm+M)`

C

`(mv)/(Nm+M)`

D

`(Nm+M)/(mv)`

Text Solution

Verified by Experts

The correct Answer is:
B
By momentum conservation (considering 'N particles of mass `m+` mass M' as system)
`mV xx N =(Nm +M)V'`
