The charges 2 q ,- q ,- q are located at the vertices of an equilateral triangle. At the circumference of the triangle
Options
- Athe field is zero but potential is not zero.
- Bthe field is non-zero but the 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 the 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
