A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulting handle. As a result the potential difference between the plates

A network of four capacitors of capacity equal to C₁ = C, C₂ = 2C, C₃ = 3C and C₄ = 4C are connected to a battery as shown in the figure. The ratio of the charges on C₂ and C₄ is

Three capacitors each of capacity 4 $$\mu $$F are to be connected in such a way that the effective capacitance is $$6\mu F.$$ This can be done by

A capacitor of capacity C₁ charged upto V volt and then connected to an uncharged capacitor of capacity C₂. The final potential difference across each will be
