Two parallel plates separated by distance d are kept at potential difference V volt. A charge q of mass m enters in parallel plates with some velocity. The acceleration of the charge particle will be

Options

A. `(qV)/(dm)`
B. `(dm)/(qV)`
C. `(qm)/(dV)`
D. `(dV)/(qm)`

Answer

A

Explanation

by def. `E=("Force")/("Charge")=(E)/(q)`
and `E=(dV)/(dx)=(V)/(d)`
`therefore F=Eq=(Vq)/(d)`
`therefore a=(F)/(m)=(Vq)/(md)`
