Question

Find the electric field intensity due to a uniformly charged spherical shell at a point (i) outside the shell and (ii) inside the shell. Plot the graph of electric field with distance from the center of the shell.

Answer 1

Electric field intensity of uniformly charged spherical shell can be found out using coulomb's law.

• Interactive force between charged particles in symmetric distribution at any distance under a non contact force can be found using Coulomb's law.
• Electric field of such a distribution can be found out from the force using the equation,  E=F/q

1) E= 1/4πε$_{0}$ $\frac{q}{r^{2} }$

     = σ/ε$_{0}$ $\frac{R^{2} }{r^{2} }$

2)E=1/4πε$_{0}$ $\frac{q}{R^{2} }$

    =σ/ε$_{0}$
