## Homework Statement

Calculate the magnitude of the field strength at point P as shown. The distance between the centers of the 1.5E-6 C and the 9.2E-6 C charges is 5.6 cm..

## Homework Equations

E = kq/r^2

E = F/Q

E = V/d

## The Attempt at a Solution

Used tan and sin of 50 to find all distances

E = kq/r^2

E = (9E9)(1.5E-6C) / (7.31E-2 m)^2

E = 2.526E6 N/C

E = kq/r^2

E = (9E9)(9.2E-6C) / (4.69E-2 m)^2

E = 2.526E6 N/C

then used those numbers to find c^2 using cosine law.

I'm not getting a correct answer (obvoiusly).

Thanks,
