The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: Both A and R are true and R is the correct explanation of A. Both A and R are true but R is NOT the correct explanation of A. A is true but R is false. A is false and R is also false. Assertion: The capacitance of a parallel plate capacitor decreases with the increase in distance between the plate of the capacitor. Reason:The capacitance of a parallel plate capacitor is C=(Aepsilon_0)/d .
