Q.A conducting sphere of radius $R$ is given charge $Q$ . The electric potential and the electric field at the centre of the sphere respectively are (NEET 2019)

Q/(4\pi\epsilon_0 R)

and zero

Zero and

Q/(4\pi\epsilon_0 R)

Both zero

Both

Q/(4\pi\epsilon_0 R)

The correct solution involves applying the fundamental concept to derive the final value step by step...
