Question

An electron is released from a negatively charged plate 0.5m away.The potential difference between the plates is 25v.

Answer 1

Explanation:

In brief, electrons are negative charges and protons are positive charges. An electron is considered the smallest quantity of negative charge and a proton the smallest quantity of positive charge.

Two negative charges repel. Also, two positive charges repel. A positive charge and a negative charge attract each other (all experimentally verified.)

Point Charge: An accumulation of electric charges at a point (a tiny volume in space) is called a point charge.

Note: When an atom loses an electron, the separated electron forms a negative charge, but the remaining that contains one less electron or consequently one more proton becomes a positive charge. A positive charge is not necessarily a single proton. In most cases, a positive charge is an atom that has lost one or more electron(s).
