Mark the correct statements.

Options

A. A given conducting sphere cannot be charged to a potential greater than a certain value.
B. A given conducting sphere can be charged to a potential less than a certain minimum value.
C. A given conducting sphere can be charged to any extent.
D. none of these

Answer

A, B

Explanation

a.,b.
If the charge is given to a conducting sphere, then an electrics field is established is the surrounding space. Magnitude of electric field is maximum ust outside the sphere. This maximum electric field may be increased to the dielectric strength of the surrounding medium. Therefore, there is a limiting value of maximum charge which can be given to the the conducting sphere cannot be charged to a potential greater than a certain value. Hence, option (a) is correct. It can be easily said that option (b) is alos correct.
