A particle of mass m and charge q is in a electric and magnetic field given by
`vecE = 2hati + 3hatj , vecB = 4hatj +6hatk`
The charged particle is shifted form the origin to the point P(x = 1, y=1) along a striaght path. The magnitude of the total work done is :

A

`(0.15)q`

B

`5q`

C

`(2.5)q`

D

`(0.35)q`

Text Solution

Verified by Experts

The correct Answer is:
B
Work done by the electric force will remain path independent and work done by magnetic field should be zero.
`therefore Q=q(2 hat i+3 hat j). (hat i+hat j) implies W=5q`.
