A thin spherical shell of radius R has charge Q spread uniformly. Which graph represents the electric field E (r) for 0 \leq r < \infty ?

Solution & Step-by-step Explanation

Inside a conducting spherical shell (r < R), the electric field E = 0 .On the surface and outside (r \geq R), the shell behaves like a point charge at the centre: E = \frac{Q}{4 π ϵ _{0} r ^{2}} .The graph is zero until r = R, then follows an inverse square decay.

Try it yourself before checking the explanation above.

A thin spherical shell of radius R has charge Q spread uniformly. Which graph represents the electric field E (r) for 0 \leq r < \infty ?

E = 0 for r < R, then drops as 1/ r^{2} for r \geq R

E increases linearly for r < R

E is constant for all r

E drops as 1/ r outside
