Question 466: Electrostatics & Capacitance

Question

Determine the electric dipole moment of the system of the three charges, placed on the vertices of an equilateral triangle, as shown in the figure :

Accepted Answer

$$\left| {{P_1}} \right| = $$ q(d)
$$\left| {{P_2}} \right| = $$ qd
|Resultant| $$=$$ 2 P cos30
o
2 qd$$\left( {{{\sqrt 3 } \over 2}} \right)$$ = $$\sqrt 3 $$  qd

Answer

$$2q\ell \widehat j$$

Answer

$$\left( {q\ell } \right){{\widehat i + \widehat j} \over {\sqrt 2 }}$$

Answer

$$\sqrt 3 \,q\ell {{\widehat j - \widehat i} \over {\sqrt 2 }}$$

Answer

$$ - \sqrt 3 \,q\ell \widehat j$$
