Two particle, each having a mass `m` are placed at a separation `d` in a uniform magnetic field `B` as shown in figure.They have opposite charges of equal magnitude `q`.At time `t=0`, the particles are projected towards each other, each with a speed `v`.
Suppose `v=2v_(m)` and they stick to each other after the collision.Describe the motion after the collision (neglect the magnetic, gravitational & electric forces between charges).

A

circular motion

B

parbolic motion

C

elliptical motion

D

straight line

Text Solution

Verified by Experts

The correct Answer is:
D
`d=2R_(m)`
`d=2(mV_(m))/(qB)`
`V_(m)=(qBd)/(2m)`
