Conductors, Capacitors, Dielectrics

Capacitance increases due to higher permittivity over vacuum.

Capacitance decreases because the dielectric absorbs some of the charge from the conductor.

Capacitance decreases exponentially with a linear increase in permittivity of dielectric material.

Capacitance remains unchanged since the shape and size of the conductor do not alter.

It decreases their mutual force.

It increases their mutual force.

It has no effect on their mutual force.

It reverses the direction of their mutual force.

The capacitance decreases by a factor of $k$.

The capacitance increases by a factor of $\frac{1}{k}$.

The capacitance remains the same.

The capacitance increases by a factor of $k$.

Reactance would decrease assuming permittivity rises at higher frequencies enhancing capacitive behavior.

Reactance would increase if permittivity decreases at higher frequencies diminishing capacitive effects.

Frequency has no impact on reactance as it's solely determined by geometric factors like plate area and spacing.

No change since reactance for an ideal capacitor should be independent of permittivity variations with frequency.

Electrostatic potential energy initially drops but recovers once dipole alignment achieves steady-state equilibrium.

Electrostatic potential energy remains unchanged because the introduction of a new material into the existing configuration should not affect the energy dynamics.

Electrostatic potential energy increases because water has a high relative permittivity that increases capacitance, leading to greater energy storage.

Electrostatic potential energy decreases since the conductive properties of water lower the overall resistance, therefore reducing the energy retained by the capacitor.

The electric field points outward from the center.

The electric field oscillates periodically.

The electric field is zero.
