Question

An electron is moving in the presence of an electric field of 400 N/C. What force does the electron experience?

Answer 1

Answer:

Explanation:

Given

Electric Field strength $E=400\ N/C$

charge of electron $q=1.6\times 10^{-19}\ C$

Force on the charge particle is given by

$F=qE$

$F=1.6\times 10^{-19}\times 400$

$F=640\times 10^{-19}\ N$

but this force will be acting in the direction opposite to the direction of Electric field because electron is negatively charged
