Question

A metal sphere of radius 1 cm is given a charge of $3.14\mu C$.Find the electric intensity at a point 1 m from the center of the sphere.

Answer 1

$q=3.14\mu C=3.14\times {10}^{-6}CE=\frac{1}{4\pi E_o}\frac{q}{x^2}9\times {10}^9\times \frac{3.14\times {10}^{-6}}{1^2}N/e2.826\times {10}^{4}N/C$
