# Thread: charges with Columbs law.

1. ## charges with Columbs law.

The charge at the coordinate origin has a value of q1 = +9.00 µC; the other two have identical magnitudes, but opposite signs: q2 = -5.50 µC and q3 = +5.50 µC.

(a) Determine the net force (magnitude and direction) exerted on q1 by the other two charges. magnitude in N
direction ° (measured counter clockwise from the x-axis)

(b) If q1 had a mass of 1.00 g and it were free to move, what would be its acceleration?
in m/s^2

As to the acceleration, that's easy. $\sum F = ma$.
