     What physical quantities may \[X\] and \[Y\] represent? (\[Y\] represents the first mentioned quantity) [NCERT 1978; MP PMT 2003]

    A)            Pressure  v/s temperature of a given gas (constant volume)

    B)                    Kinetic energy v/s velocity of a particle

    C)                    Capacitance v/s charge to give a constant potential

    D)            Potential v/s capacitance to give a constant charge

    Correct Answer: D

    Solution :

               From \[V=\frac{Q}{C}\].  For constant Q, \[V\propto \frac{1}{C}\]  i.e. ?V? varies hyperbolically with C.
