Question

Two charges are placed at a distance apart if a glas slab is placed between them force between them will

Answer 1

Answer:

Force will decreases because when medium is inserted between then it will reduces the forces by its permitivity.

the force becomes

Fe m = Fe/ ε r

please mark me as brainliest.......☺️
