An earthed metal P is placed directly above the plate of a charged electroscope as shown.

An earthed metal P is placed directly above the plate of a charged electroscope as shown.

State and explain what is observed when:
i) P is slid slowly sideways.
ii) P remains fixed in its position but a slab of paraffin was is slid slowly between the plates.

i) Divergence increases capacitance decreases in area of overlap.
ii) Paraffin wax acts as a dielectric this increases the capacitance,hence V decreases and therefore falls.
