MCQ

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
✓
Potential $v/s$ capacitance to give a constant charge

✓

Answer

Correct option: D.

Potential $v/s$ capacitance to give a constant charge

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