## Homework Statement

Two charges, Q

_{1}= 4*10

^{-8}and Q

_{2}= 2.7*10

^{-8}are 3.25 m apart.

What is the electric field magnitude halfway between them?

## Homework Equations

E = kQ/r

^{2}

## The Attempt at a Solution

E

_{1}= k (4*10

^{-8}C)/(1.63m)

^{2}

= 135 N/C

E

_{2}= k (2.7*10

^{-8}C)/(1.63m)

^{2}

= 91.4 N/C

135 N/C - 91.4 N/C =

**43.5 N/C**

Is this correct?
