Assertion: A positively charged rod is held near a neutral conducting solid sphere as illustrated below. The sphere lies on a insulated stand. The potential of ground (or earth) is zero. The potential at point `A` (point `A` need not be centre of the sphere) is higher compared to potential of gound (earth).
Reason: In this situation of assertion, the potential at the centre of conducting sphere is positive. the solid sphere being conducting, potential at each point in the sphere is same.
A. If both assertion and reason are true and reson is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assertion and reason both are false.
