Three charges, each + q, are placed at the corners of an isosceles triangle ABC of sides BC and AC, each equal to 2a. D and E are the midpoints of BC and CA The work done in taking a charge Q from D to E is:
- zero
- \(\frac{3 q Q}{4 \pi \varepsilon_{0} a}\)
- \(\frac{3 q Q}{8 \pi \varepsilon_{0} a}\)
- \(\frac{q Q}{4 \pi \varepsilon_{0} a}\)
Answer
(A) zero
