An electron enters uniform electric field maintained by parallel plates and of value `E Vm^(-1)` with a velocity `v ms^-(1)` the plates are separated by a distance dmetre, then acceleration of the electron in the field is :

Options

A. `(Ee)/(m)`
B. `(-Ee)/(m)`
C. `(Ed)/(md)`
D. `Ee (d)/(m)`

Answer

A

Explanation

`F = eE`
Therefore, acceleration in electron due to force F
`a = (F)/(m) = (eE)/(m)`
