Question

Four small point objects are located at the corners of a square of side $L$ . Each object has a charge $q$ . Find an expression for the electric potential for locations on the axis that goes through the centre of the square and perpendicular to its surface.
$E_{z} = \frac{4 k_{e} q}{(z^{2} + 0.5 L^{2})^{3 / 2}}$
$E_{z} = \frac{4 k_{e} q}{(z^{2} + 0.5 L^{2})^{1 / 2}}$
$E_{z} = \frac{4 k_{e} q z}{(z^{2} + 0.5 L^{2})^{3 / 2}}$
$E_{z} = \frac{4 k_{e} q z}{(z^{2} + L^{2})^{3 / 2}}$

A

E_{z} = \frac{4 k_{e} q}{(z^{2} + 0.5 L^{2})^{3 / 2}}

B

E_{z} = \frac{4 k_{e} q}{(z^{2} + 0.5 L^{2})^{1 / 2}}

C

E_{z} = \frac{4 k_{e} q z}{(z^{2} + 0.5 L^{2})^{3 / 2}}

D

E_{z} = \frac{4 k_{e} q z}{(z^{2} + L^{2})^{3 / 2}}
