Question

The force experienced by a proton placed in an upward electric field of 4*10^4NC

Answer 1

Given :

Charge of proton = 1.6 * 10 ^ (-19) C

The strength of the electric field = 4 * 10 ^ 4 N/C

To find :

The force experienced by the proton in that electric field .

Solution :

Electric Force , F = charge * electric field

=> F = q * E

=> F = 1.6 * 10 ^ (-19) C * 4 * 10 ^ 4 N/C

=> F = 6.4 * 10 ^ (-15) N

The force experienced by the proton is 6.4 * 10 ^ (-15) N .
