Answer:
Explanation:
Given
Electric Field strength [tex]E=400\ N/C[/tex]
charge of electron [tex]q=1.6\times 10^{-19}\ C[/tex]
Force on the charge particle is given by
[tex]F=qE[/tex]
[tex]F=1.6\times 10^{-19}\times 400[/tex]
[tex]F=640\times 10^{-19}\ N[/tex]
but this force will be acting in the direction opposite to the direction of Electric field because electron is negatively charged
