A) The field is zero but potential is non-zero
B) The field is non-zero but potential is zero
C) Both field and potential are zero
D) Both field and potential are non-zero
Correct Answer: B
Solution :
Obviously, from charge configuration, at the centre electric field is non-zero. Potential at the centre due to 2q charge \[{{V}_{2q}}=\frac{2q}{r}\]You need to login to perform this action.
