| ASSERTION: The capacity of conductor, under given circumstances remains constant irrespective of the charge present on it. |
| REASON: Capacity depends on size and shape of conductor and also on the surrounding medium. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
Charge present on a conductor determines its potential. Capacity is a function of size and shape of the conductor and of the surrounding medium. Capacitance in case of parallel plate capacitor \[C=\frac{K\,{{\varepsilon }_{0}}A}{d}\], where K is dielectric constant of medium, A is area of plates and d is distance between them.
