Question

Consider an ideal parallel plate capacitor of capacitance C, charged with chargeQ and isolated. Choose the correct statement. A. If a dielectric with relative permittivity , > 1 is inserted between the plates the accumulated energy decreases. B. If a dielectric with relative permittivity , > 1 is inserted between theplates the accumulated energy increases. C. When a dielectric with relative permittivity &> 1 is partially inserted between the plates there is a force that pushes it outside. D. When a dielectric with relative permittivity , > 1 is partially inserted be-tween the plates the charge accumulated on the capacitor plates changes. [4]
