Question

A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw

based on this description?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field.
The electric field points to the right because the force on a negative charge is in the same direction as the field
O No conclusion can be drawn because the sign of the charge creating the field is unknown
O No conclusion can be drawn because the amount of charge on the test charge is unknown

Answer 1

The correct option is (A).

Step-by-step explanation:

The direction of electric force is in the direction of electric field. The electric force acting on a charged particle is given by :

F = qE, q is magnitude of charge

We have, a negative test charge experiences a force to the right as a result of an electric field. It would mean that the electric field points to the left because the force on a negative charge is opposite to the direction of the field.
