# Electric Field Strength: Two Charged Spheres

APPH12-T1HHUA

Two charged spheres ($q_1=+4.5\times10^{-6}\text{ C}$ and $q_2=-1.7\times10^{-6}\text{ C}$) are located so that their center-to-center distance is $64\text{ cm}$.

What is the electric field at the point half way between the spheres?

A

$5.5\times10^5\text{ N/C}$ to the left

B

$2.5\times10^5\text{ N/C}$ to the left

C

$2.5\times10^5\text{ N/C}$ to the right

D

$5.5\times10^5\text{ N/C}$ to the right
