Calculate the electric potential at a point

5\,\text{cm}

away from a point charge of

+2\,\mu\text{C}

in vacuum. (Take

\dfrac{1}{4\pi\epsilon_{0}}=9\times10^{9}\,\text{N m}^2\!\text{/C}^2

.) (a)

3.6\times10^{4}\,\text{V}

(b)

-3.6\times10^{5}\,\text{V}

(c)

3.6\times10^{5}\,\text{V}

(d)

7.2\times10^{6}\,\text{V}
