Question

A spherical conductor of radius 10 cm has a charge of 3.2 $ \times $ 10^-7 C distributed uniformly. That is the magnetude of electric field at a point 15 cm from the centre of the sphere?
$\left( {{1 \over {4\pi {\varepsilon _0}}} = 9 \times {{10}^9}N{m^2}/{c^2}} \right)$

1.28 $ \times $ 10⁵ N/C

1.28 $ \times $ 10⁶ N/C

1.28 $ \times $ 10⁷ N/C

1.28 $ \times $ 10⁴ N/C
