Question

the potential difference between two plates separated by a distance of 1mm us 100v the force on electron placed between the plate is ​

Answer 1

Answer:

Here up and down is answer make me brainliest .

Explanation:

Since plates are separated by small distance, compared to plates dimensions, the electric field between them is uniform and given by E=V/d=100V/(10^-3m)=(10^5 V/m).

The force on electron placed in this field is F=-eE=-(1.6x10^-19C)(10^5 V/m)=-1.6x10^-14 N.

The negative sign indicates that direction of force is opposite to that of field.
