Question
Four charges of 1μC, 2μC, 3μC, and - 6μC are placed one at each corner of the square of side 1m.
The square lies in the x-y plane with its centre at the origin.
The square lies in the x-y plane with its centre at the origin.
Options
A.The electric potential is zero at the origin.
B.The electric potential is zero everywhere along the z-axis only if the sides of the square are parallel to x and y axis.
C.The electric potential is zero everywhere along the z-axis for any orientation of the square in the x-y plane.
D.The electric potential is not zero along the z-axis except at the origin.
Solution
Here total charge is zero.
Any point on z-axis, having the same distance from the each verses of a square. So the potential due to all is zero at that point.
Any point on z-axis, having the same distance from the each verses of a square. So the potential due to all is zero at that point.
