Correct option is A
Correct answer is A
Explanation:
For electrostatic shielding:
· Due to the absence of electric charges inside a cavity surrounded by a conductor, the electric field inside the cavity is zero.
· Since the electric field is zero everywhere inside the cavity, the potential does not vary and remains constant at all points.
Hence, both S and S are true. Furthermore, S (the electric field being zero) is the cause of S (the constant potential at all points inside the cavity).
