A particle of mass m and charge q is accelerated through a potential differece V to a velocity `vecv` towards south. The particle enters a region with both a magnetic field `vecB` (pointing eastwards) and electric field `vecE` (pointing downwards). The particle travels with a constant velocity through this region. The potential difference V through this region should be equal to

A

B

`2mE//qB`

C

E/qB
