Question

A positive charge of 6.0 x 10-4 C is in an electric field that exerts a force of 4.5 x 10 -4 on it. What is the strength of the electric field?

Answer 1

Electric field is defined as force per unit charge.

So it is given by

`F = q E`

now we can find electric field by

`E = (F)/(q)`

`E = (4.5*10^(-4))/(6 * 10^(-4))`

`E = 0.75 N/C`

So field strength is 0.75 N/C.
