## Homework Statement

Two point charges, Q1 and Q2 are 6m apart. The electric field intensity a point A, midway between the two charges is 5 N/C directed toward Q2, and the potential at the same point is 45V. Find:

a) the magnitude of Q1

b) the magnitude of Q2

## Homework Equations

## The Attempt at a Solution

This is what I got so far.

V

_{A}= k [(Q1+Q2)/r]

45 V = 9x10

^{9}[(Q1+Q2)/3]

Then I'm stuck at what to do next and what to do with E = 5 N/C
