PHXII02:ELECTROSTATIC POTENTIAL AND CAPACITANCE

359418 The electrostatic potential on the surface of a charged conducting sphere is 50 \(V\). Two statements are made in this regard.
\({S_1}\) : At any point inside the sphere, electric intensity is zero.
\({S_2}\) : At any point inside the sphere, electrostatic potential is 50 \(V\).
Which of the following is a correct statement?

1 \({S_1}\) is true, \({S_2}\) is also true and \({S_1}\) is the cause of \({S_2}\)
2 \({S_1}\) is true but \({S_2}\) is false.
3 \({S_1}\) is true \({S_2}\) is also true but the statements are independent.
4 Both \({S_1}\) and \({S_2}\) are false.

359419 Assertion :
Two concentric conducting spherical shells are charged. The charge on the outer shell is varied keeping the charge on inner shell constant, as a result the electric potential difference between the two shells does not change.
Reason :
In the situation of assertion, the electric field in the region between both the shells depends only on the charge existing on the inner shell.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
