Question

which is the best definition of electric charge? it is a force of attraction and repulsion by magnetic materials. it is a force of attraction based on an objects mass. it is the flow of electrons that have a negative charge to protons that have a positive charge.

Explanation:

Electric charge is the property of matter that causes it to experience a force when placed in an electromagnetic field. Electrons have a negative charge and protons have a positive charge, and the flow of these charged particles (like electrons) is related to electric charge concepts. The first option describes magnetism (force by magnetic materials), the second describes gravitational force (based on mass). The third option correctly relates to electric charge concepts involving electrons (negative) and protons (positive).

Answer:

It is the flow of electrons that have a negative charge to protons that have a positive charge.
