A spherical conductor of radius $\displaystyle 10$ cm has a charge of $\displaystyle 3.2 \times 10^{-7} \mathrm{C}$ distributed uniformly. What is the magnitude of electric field at a point $\displaystyle 15$ cm from the centre of the sphere ?
$$\left(\frac{1}{4 \pi \epsilon_0}=9 \times 10^9 \mathrm{~N} \mathrm{~m}^2 / \mathrm{C}^2\right)
$$
