Explanation / Answer

(A) Force due to negative charge will be equal.

magnitude of force due to 1 charge, F = k Q q / (a^2 + (a + b)^2)

cos(theta) = (a + b) / sqrt[ a^2 + (a + b)^2]

Fx- = 2 F cos(theta) = 2 k Q q (a +b) / [ a^2 + (a + b)^2 ]^(3/2)

(b) Fx = - k Q q / (a + b)^2

(c) Fx = - k Q q / (2a + b)^2

(D) Fx- = (2 x 9 x 10^9 x 120 x 10^-6 x 6 x 10^-6) (0.075 + 1.1) / (0.075^2 + 1.175^2)

= 9.33 N

due to nearest = (9 x 10^9 x 120 x 10^-6 x 6 x 10^-6) / (1.175^2) = - 4.6935 N

due to farther = (9x 10^9 x 120 x 10^-6 x 6 x 10^-6) / (1.25^2) = - 4.15 N

net force = 9.33 - 4.69 - 4.15 = 0.49 N
