negative

when electrons are scraped from hair by brushing, the hair's net charge is

(4e)(6e)/d²

two charges q1 = +4e and q2 = +6e separated by distance d exert force proportional to

four times

doubling distance between charges changes the force to

aluminum

Which is a typical conductor?

charge in an isolated system is conserved; electrons are transferred but not created or destroyed

Which of the following states conservation of charge correctly?

superconductor

A material with zero electrical resistance so current can flow indefinitely is called a

Bubringing a charged object near a conductor to cause charge redistribution without contact.

Charging by induction involves
