Two identical particles having the same ...

Two identical particles having the same mass m and charges `+q` abnd `-q` separeted by a distance d enter in a unifrom magentic field B directed perpendicular to paper inwards with speeds `v_(1)` and `v_(2)` as shown in figure. The particles will not collide if (Ignore electrosatatic force)

A

`dgt m/(Bq) (v_1 + v_2)`

B

`dlt m/(Bq) (v_1 + v_2)`

C

`dgt (2m)/(Bq) (v_1 + v_2)`

D

`v_1 = v_2`

Text Solution

Verified by Experts

The correct Answer is:
c
The particle will not collide if
`dgt2(r_1+r_2)`
or `dgt2((mv_1)/(Bq)+(mv_2)/(Bq)) or dgt(2m)/(Bq) (v_1+v_2)`
