What physical quantities may $X$ and $Y$ represent ? ($Y$ 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

Solution

(d) From $V = \frac{Q}{C}$. For constant $Q$, $V \propto \frac{1}{C}$ i.e. ‘$V$’ varies hyperbolically with $C$.
