Question

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

Open in App

Solution

$q = 3.14 μ C = 3.14 \times 10^{- 6} C E = \frac{1}{4 π E_{o}} \frac{q}{x^{2}} 9 \times 10^{9} \times \frac{3.14 \times 10^{- 6}}{1^{2}} N / e 2.826 \times 10^{4} N / C$
