Question

The parallel plates in a capacitor, with a plate area of 8.50 cm2 and an air-filled separation of 3.00 mm, are charged by a 6.00 V battery. They are then disconnected from the battery and pulled apart (without discharge) to a separation of 8.00 mm. Neglecting fringing, find (a) the potential difference between the plates, (b) the initial stored energy, (c) the final stored energy, and (d) the work required to separate the plates

Answer:(a). The charge is

(b). The initial stored energy is

(c). The final stored energy is

(d). The work required to separate the plates is

Explanation:Given that,Area = 8.50 cm²

Distance = 3.00 mm

Potential = 6.00 V

Distance without discharge = 8.00 mm

(a). We need to calculate the capacitanceUsing formula of capacitancePut the value into the formula

We need to calculate the chargeUsing formula of chargePut the value into the formula

(b). We need to calculate the initial stored energyUsing formula of initial energy(c). We need to calculate the capacitanceUsing formula of capacitancePut the value into the formula

We need to calculate the final stored energyUsing formula of initial energy(d). We need to calculate the work doneUsing formula of work donePut the value in the formula

Hence, (a). The charge is(b). The initial stored energy is(c). The final stored energy is(d). The work required to separate the plates is
