A conducitng rod `AB` of length `l = 1 m` moving at a velcity `v = 4 m//s` making an angle `30^(@)` with its length. A uniform magnetic field `B = 2T` exists in a direction perpendicular to the plane of motion. Then :

`V_A-V_B=8V`

`V_A-V_B=4V`

`V_B-V_A-8V`

`V_B-V_A=4V`

Text Solution

Verified by Experts

The correct Answer is:

`e=Blv sin theta`
