Question

The electric filed due to a uniformly charged spherical shell of charge 'Q' and radius 'R' at a distance 'r' is for $r<R$, and for $r>R$.

• A. $\frac{kQ}{r^2}$
• B. $\frac{k{Q}^2}{r^2}$
• C. $zero$
• D. $\frac{kQ}{r}$

Answer 1

Answer: (A), (C)

The correct options are
A $\frac{kQ}{r^2}$
C $zero$

As explained in the video, field inside a uniformly charged spherical shell is zero. Field outside the spherical shell is $\frac{Q}{4\pi {ϵ}_0{r}^2}$
