Three point charges of ( +2 q,+2 q ) and ( -4 q ) are placed at the corners ( A, B ) and ( C ) of an equilateral triangle ( ABC ) of side ' ( x ) '. The magnitude of the electric dipole moment of this system is

Question

Quantrex Academy · Accepted Answer

Correct answer: B. ( 2 3 ) qx

Net dipole moment [ array l = 4 p²+4 p²+2 (4 p² ) 60^ = 4 p²+4 p²+8 p² 1 2 = 4 p²+4 p²+4 p² = 12 p² =2 3 p array ] Therefore, net dipole moment ( 2 3 q x )
