A uniform magnetic field existsin region...

A uniform magnetic field existsin region given by `vec(B) = 3 hat(i) + 4 hat(j)+5hat(k)`. A rod of length `5 m` is placed along `y`-axis is moved along `x`- axis with constant speed `1 m//sec`. Then the magnitude of induced `e.m.f` in the rod is :

zero

`25 v`

`20 v`

`15 v`

Text Solution

Verified by Experts

The correct Answer is:

`epsilon=vecB(vecVxxvecl)`
`=(3hati+4hatj+5hatk)[1hatixx5hatj]`
`epsilon=25 "volt"`
