Solution:
Here, resulting graph represent straight line.
Here, Q is along Y axis and V is along X axis .
Here, Tangent is m = Q / V = 20/4 = 5 uF which is equal Capacitance. [Q=CV]
a) Capacitance is 5uF
b) Potential Energy is stored in the capacitor when V= 1 volt, is U = 1/2 CV^2
Therefore, U = 1/2*(5*10^-6)*(1) = 2.5 uJ [Answer]

Explain why capacitance ?C depends neither on the stored charge ?q nor on the potential difference ?V between the plates of a capacitor. Capacitance is determined only by the physical properties of the capacitor. The stored charge ?q and the potential difference ?V are independent of the size and shape of the capacitor. The net charge on a capacitor is zero, and therefore the potential difference ?V cancels. The stored charge ?q is inversely proportional to the potential difference ?....
