1.

Consider a capacitor shown in Fig. 1 . If we pull the plates of capacitor to a final position as show in Fig ,2 then we must performwork against electric force. For this situation . Mark out the correct statement .[take areas of plates as A]

Answer»

WORK done is `(Q^2)/(2epsilon_(0)A)(d_(2)-d_(1))` and is stored in VOLUME `A(d_(2)-d_(1))`
Work done is `+(Q^2)/(2epsilon_(0)A)(d_(2)-d_(1))` and is stored in volume `Ad_2`.
Work done is+ `(epsilon_0AV^2)/(2)((d_2-d_1)/(d_1d_2))`and is stored in volume `A(d_2-d_1)`
Work done is+ `(epsilon_0AV^2)/(2)((d_2-d_1)/(d_1d_2))`and is stored in volume `Ad_2`
