Answer to Question #148332 in Electricity and Magnetism for Sneha

Question

What is charge write it's properties.

Answer 1

Charge is a property of some elementary particles that gives rise to an interaction between them and consequently to the host of material phenomena described as electrical. Charge occurs in nature in two forms, conventionally described as positive and negative in order to distinguish between the two kinds of interaction between particles. Two particles that have similar charges (both negative or both positive) interact by repelling each other; two particles that have dissimilar charges (one positive, one negative) interact by attracting each other.

Properties of charge:

1. Conservation of charge – the sum of all charges of a system does not change with time.

2. The carriers of electric charge are many subatomic particles such as protons and electrons (as well as antiprotons and positrons) and some metastable particles as π-mesons, K-mesons, muons, etc.

3. Charged subatomic particles have the same electric charge in magnitude.
