Physics - Capacitor Question with Solution | TestHub

A parallel combination of two capacitors of capacities ' $2\mathrm{C}$ ' and ' $\mathrm{C}$ ' is connected across $5\mathrm{V}$ battery. When they are fully charged, the charges and energies stored in them be ' ${\mathrm{Q}}_1$ ', ' ${\mathrm{Q}}_2$ ' and ' ${\mathrm{E}}_1$ ', ' ${\mathrm{E}}_2$ ' respectively. Then $\frac{{\mathrm{E}}_1-{\mathrm{E}}_2}{{\mathrm{Q}}_1-{\mathrm{Q}}_2}$ in $\mathrm{J}/\mathrm{C}$ is (capacity is in Farad, charge in Coulomb and energy in $J$ )
