Anegative 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?
a. the electric field points to the left because the force on a negative charge is opposite to the direction of the field.
b. the electric field points to the right because the force on a negative charge is in the same direction as the field.
c. no conclusion can be drawn because the sign of the charge creating the field is unknown.
d. no conclusion can be drawn because the amount of charge on the test charge is unknown.

A.The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

Explanation:

As we know that electrostatic force on a charge in external electric field is given as

so here the force and electric field will be in same direction if charge is positive and if the charge is negative then force will be in opposite direction to the electric field.

So we know that since the electron is negatively charged so the force on electron must be opposite to the electric field present in that region.

So correct answer will be

A.The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
