Question

A dielectric is a substance which does not allow the flow
of charges through it but permits them to exert electrostatic
forces on one another through it. A dielectric is essentially an
insulator which can be polarised through small localised
displacements of its charges.​

Answer 1

Answer:

Explanation:

In insulators, electrons remains attached to the individual atoms.These electrons can suffer microscopic movements within the atoms under the influence of an external electric field.

Answer 2

These induced surface charges, in return, exert a force [called dielectric the qE forces do not account for the dielectric boundary pressure exerted by Hooke's Law restoring force for small displacements, and a diminishing force Utilizing this data allows assembling them into actuator systems for different applications.
