An electric charge `+q +q` moves with velocity `vecv = 3hati + 4hatj + hatk,` in an electromagnetic field given by : `vecE = 3hati + hatj + 2hatk` and `vecB = hati +hatj + 3hatk`. The y-component of the force experienced by `+q` is :

A

`7 q`

B

`5 q`

C

`3 q`

D

`11 q`

Text Solution

Verified by Experts

The correct Answer is:
1
`vecF=q[vecE+vecvxxvecB]=F_(y)=7q hatj`
