Question 940: Electrostats & Capacitance

Question

Three charges, each +q, are placed at the corners of an isosceles triangle ABC of sides BC and AC, 2$$a$$. D and E are the mid points of BC and CA. The work done in taking a charge Q from D to E is

Accepted Answer

AC = BC
V
D
= V
E
We have, W = Q (V
E
Ã¢ÂÂ V
D
)
$$ \Rightarrow $$ W = 0

Answer

$${{3qQ} \over {4\pi {\varepsilon _0}a}}$$

Answer

$${{3qQ} \over {8\pi {\varepsilon _0}a}}$$

Answer

$${{qQ} \over {4\pi {\varepsilon _0}a}}$$

Answer

zero
