Q1.The electric potential inside a uniformly charged thin spherical shell of
radius 20 cm is 10 V. The charge on the shell is​.

Answer 1

Explanation:

Given:

The electric potential inside a uniformly charged thin spherical shell of radius 20 cm is 10 V.

To find:

Charge on shell?

Calculation:

Let the charge on shell be "q".

Now, we know that potential inside a shell is equal to the potential at the surface of the shell.

$V = \dfrac{kq}{r}$

$\implies 10= \dfrac{(9 \times {10}^{9} )q}{ (\frac{20}{100} )}$

$\implies 10= 4.5\times {10}^{10} \times q</p><p>$

$\implies q = \dfrac{1}{4.5} \times {10}^{ - 9}$

$\implies q = 0.22 \times {10}^{ - 9} \: C$

$\implies q = 0.22 \: nC$

So, charge on shell is 0.22 nC.

Answer 2

the sperical shell of radius 20cm and uniform chare is 19 us calculate the electric field inside the sperical shell
