(a) The direction of the net electric field at the center of the square is (iv) downward direction: The electric field due to positive charge is directed away from the charge along the line joining the charge and center of the square.

## When a point charge of +q is placed on one corner of a square?

When a point charge of +q is placed on one corner of a square, an electric field strength of 2 N/C is observed at the center of the square. Suppose three identical charges of +q are placed on the remaining three corners of the square.

What is the direction of the electric field at the origin?

Since the test charge will repelled by a positive charge and attracted to a negative, the e field is defined as going outward from a positive charge and inward toward a negative charge.

How are the magnitude and direction of an electric field determined?

The Direction of the Electric Field Vector The magnitude of the electric field vector is calculated as the force per charge on any given test charge located within the electric field. The force on the test charge could be directed either towards the source charge or directly away from it.

What is k in coulomb’s law?

The symbol k is a proportionality constant known as the Coulomb’s law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. If the charged objects are present in water, the value of k can be reduced by as much as a factor of 80.
