Q. What physical quantities may $X$ and $Y$ reprsent? ($Y$ represents the first mentioned quantity)
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
Explanation
(d) From $V = \frac{Q}{C}.$ For constant $Q,\ V \propto \frac{1}{C}\ i.e.\ 'V'$ varies hyperbolically with $C$
