Question

A single charge at distance to. What is the relationship of force and electric field with distance r.

Answer 1

Answer:

the distance r away has a magnitude k|q|r2 and point away from the charge.

Explanation:

the electrostatic force exerted by point charge on a test charge at r depend upon both distance as well as charge. the e. field is defined to E=FqE=Fq

F is Coulomb's or electrostatic force exerted on a small positive test charge q
