A potential difference of V volt is applied between two parallel plates
P1 and
P2, separated by a distance d, with the planes of plates being parallel to xOz plane as shown in the Figure. A uniform magnetic field
B^k is applied out of the cross- section, perpendicular to it. A particle of charge q and mass m is released at rest from O
(0,0,0) on the plale
P1. it is found that the particle never touches the plate
P2 if
d≥1B√nVmq What is the value of
n?
