A condenser of $2 μ F$ capacitance is charged steadily from $0$ to $5 C$ . Which of the following graph represents correctly the variation of potential difference $(V)$ across its plates with respect to the charge $(Q)$ on the condenser?

Options:

Answer:

Solution:

The charge on a condenser is given by $Q = C V$ .
$\Rightarrow V = \frac{1}{C} Q$
Since the capacitance depends on the construction of the condenser, it is constant. Therefore, the graph will be straight line with slope $= \frac{1}{C}$ .
Slope $= \frac{1}{C} = \frac{1}{2 \times 10^{- 6}} = 5 \times 10^{5}$
