A particle of charge +q and mass m moving under the influence of uniform electric field `Ehati` and uniform magnetic field `BhatK` follows a trajectory from P to Q as as shown in figure. The velocities at P and Q are `vhati` and `-2vhatj` of the following statements is/are correct ?

A

`E=(3)/(4)(mv^(2))/(qa)`

B

Rate of work done by electric field at `P` is `(3)/(2)(mv^(3))/(a)`

C

Rate of work done by electric field at `P` is not zero

D

Rate of work done by both field at `Q` is not zero

Text Solution

Verified by Experts

Use work energy theorem, magnetic force being perpendicular to velocity can not do any work.
