Force on charge 3q by 2q = k(3q)(2q) /a^2
= 9*10^9*6*6*(4.6*10^-6)^2 / 0.15^2
= 50.784 N ( -ve y-direction )
Force on charge 3q by 4q = k(3q)(4q) /a^2
= 9*10^9*12*(4.6*10^-6)^2 / 0.15^2
= 101.568 N ( -ve x-direction )
Force on charge 3q by q = K*3q*q / (sqrt 2 a) ^2
= 9*10^9*3*(4.6*10^-6)^2 / 2*(0.15)^2
= 12.696 N ( angle 45o )
Net force in X-direction = 101.568 + 12.696 cos 45 = 110.5 N
Net force in Y-direction = 50.784 + 12.696 sin 45 = 59.76 N
net force on charge 3q = sqrt(110.5^2 + 59.76^2) = 125.6 N
direction = tan^-1 ( 59.76 / 110.5) = 28.40
direction = (90 + 28.4) = 118.4o below the horizontal in clockwise direction
