Question

A downward force of 8.4N is exerted on a -8.8uC charge. What are the magnitude and direction of the electric field?

Answer 1

E = F/q

F = 8.4 N
Q = -8.8 uC


E = 8.4 N / - 8.8 x 10^6 C
= -9.5 x 10^-7 N/C



If the result of this kind of equation resulted in negative, the direction of the electric field will be upward

hope this helps
