An electric charge `+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

`2 q`

Text Solution

Verified by Experts

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