Question

Six point charges are kept at the vertices of a regular hexagon of side L and centre O, as shown in the figure. Given that K = , which of the following statement(s) is (are) correct?
                              

Options

A.The electric field at O is 6K along OD.
B.The potential at O is zero.
C.The potential at all points on the line PR is same.
D.The potential at all points on the line ST is same.

Solution



Line PR is perpendicular bisector of all the dipoles
At point O:
