When a metallic spherical shell of radius 20 cm is charged, the potential on its surface is found to be 5 V . The potential at a point 10 cm from the centre of the spherical shell is :
- A 5 V
- B 1.5 V
- C 10 V
- D 2.5 V
Answer & Solution
Correct Answer
(A) 5 V
Step-by-step Solution
Detailed explanation
For a charged metallic spherical shell of radius \(R\), the electric potential \(V\) at any point inside the shell (at a distance \(r < R\) from the centre) is equal to the potential at the surface of the shell. The potential at the surface is given as \(V_{surface} = 5\) V,…
