Answer :

GinnyAnswer

Final answer:

An electric field is the force per unit charge acting on a test charge, which can have any value or sign. It helps determine the force direction and magnitude on positive or negative test charges placed in the field.


Explanation:

Electric Field: An electric field is defined as the force per unit charge acting on a test charge. This means that a test charge can be of any value or sign, it does not have to be 1 coulomb or positive.

For example, the force per unit charge on a positive or negative test charge placed in an electric field generated by a source charge helps determine the direction and magnitude of the force experienced by the test charge.

Understanding the concept of electric fields plays a crucial role in calculating forces and interactions between charges in physics.
