A) \[\frac{eqQ}{8\pi \,{{\varepsilon }_{0}}a}\]
B) \[\frac{qQ}{4\pi {{\varepsilon }_{0}}a}\]
C) zero
D) \[\frac{3qQ}{4\pi {{\varepsilon }_{0}}a}\]
Correct Answer: C
Solution :
Here, AC = BC As D and E are the mid points of BC and CA, the potential of these points should be equal. \[{{V}_{D}}={{V}_{E}}=V\] The work done in talking a charge Q from D to E \[W=Q[{{V}_{E}}-{{V}_{D}}]=Q[V-V]=0\]You need to login to perform this action.
