Question

Electric field exerts force on ?

Answer 1

An electric force is the attractive or repulsive interaction between any two charged materials. Newton's laws of motion, like any other force, describe its effect on objects. The object's acceleration will then be calculated using the net force.

Complete answer:
The external field that surrounds each electric charge and exerts force on all other charges in the field, either attracting or repelling them, is known as an electric field (or E-field). Electric fields are generated by electric charges or magnetic fields that change over time. The electric field is a vector field that associates the (electrostatic or Coulomb) force per unit of charge exerted on an insignificantly small positive test charge at rest at each point in space with each point in space.

At some point in space, the Coulomb force on a charge of magnitude q is proportional to the product of the charge and the electric field at that point $F = qE$. In the SI system, the electric field is measured in newtons per coulomb$(N.{C^{ - 1}})$ or volts per metre $(V.{M^{ - 1}})$; the SI base units are $Kg.m.{s^{ - 3}}{A^{ - 1}}$ .

Hence, when charged particles are in a state of rest or motion, the electric field exerts force on them.

Note: Electric fields are important in many aspects of physics, and they are used in electrical technology on a daily basis. The electric field, for example, is the attractive force that holds the atomic nucleus and electrons together in atoms in atomic physics and chemistry. That is also the force that causes chemical bonds between atoms to form molecules.
