Three charges 2 q ,- q and -q are located at the vertices of an equilateral triangle. At the centre of the triangle
Options
- Athe field is zero but potential is non-zero.
- Bthe field is non-zero but potential is zero.
- Cboth field and potential are zero.
- Dboth field and potential are non-zero.
Correct answer
B. the field is non-zero but potential is zero.
Step-by-step solution
From charge configuration, at the centre electric field is non-zero. Potential at the centre due to 2 q charge V_ 2 q = 2 q r and potential due to -q charge V_ -q =- q r (r= distance of centre point ) total potential V = V _ 2 q + V _ - q + V _ - q =0
