Charges Q, Q, and q lie on the corners of an equilateral triangle with sides of length a. Charge q lies on the top corner with Q and Q on the left and right corners.
(a) What is the force on the charge q?
(b) What must q be for E to be zero half-way up the altitudeat P?
F=(1/4πε) * (q1q2/r2)
E = (1/4πε) * (q/r2)
The Attempt at a Solution
(a) F = qQ / (4πεa2) iy
(b) Eq = q / (4πε (3/16 a2)) iy
and EQ = Q / (4πε (7/16 a2)) iy
I just wanted to know if the attempts are in proportion to the required?
Thanks alot in advance.
