Question

electric charge q,q and -2q are placed at the corners of an equilateral triangle of side 'a' find electric dipole moment of the system?​

Answer 1

Answer:

Explanation:

Configuration of charges:

Imagine charges at C(−2Q) be splited into charges of (−Q) each so that (AC) and (BC) form two dipole systems.

Now, dipole moment is:

⇒P 1 = QA = p 2,

using vector addition :

⇒P net=√P²1+P²2+2+P1P2cos θ  [θ=60°],

⇒P net=QA√3.

Hope it helps.
