Which change increases the electric force between objects?
a) two neutral objects are moved closer together.
b) electrons are added to two negatively charged objects.
c) two oppositely charged objects are moved farther apart.
d) the charge on two positively charged objects is reduced.

By definition we have that the electric force is given by:

Where,

k: proportionality constant

q1: electric charge of object 1

q2: electric charge of object 2

d: distance between both objects

Therefore, to increase the electric power there are two possible cases:

1) Add more load to each object

2) Decrease the distance between objects.

The option that increases the electric force for this case is:

Electrons are added to two negatively charged objects.

This is because the values of q1 and q2 increase.

A change that increases the electric force between objects is:

B) Electrons are added to two negatively charged objects.

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.

radiation

explanation:

heat is transmitted by radiation
