Solving a problem in physics section 70 point 3 electr

3. A flat air condenser with a plate area of 100 cm2 and a gap of 5 mm is charged up to a potential difference of 900 V. Without disconnecting from the voltage source, the plates are pushed apart to a distance of 1 cm between them. Determine the electric field strength, energy and volumetric energy density of the capacitor before and after the expansion of the plates.
