You notice electric field lines going towards an isolated charged object in a radial manner. What is the sign of the net charge on the object?a. negative.b. positive.c. neutral.

Sagot :

Answer:

The correct answer is a

Explanation:

The electric field is given by the relation

         F = q E

where The force is the Coulomb force and q is a positive test charge, therefore the electric field has the same direction as the electric force.

Consequently if the charge is positive the field must go out of the charge, if the charge is negative the electric field must be directed towards the charge.

Consequently, in this exercise we are told that the lines are directed towards the load, therefore the load must have a negative sign.

The correct answer is a
