What is the net electric force on charge B in FIGURE?

The total electric force on charge,

When two charged particles, one with charge and also the other with charge , are separated by a distance , they exert forces on one other, with the force decreasing because the magnitude of the cost increases. This force is described by Coulomb's law, which is provided by equation.

is that the electrostatic constant, which is capable . determines the charge of every sphere. by converting the unit to coulomb.

Each of and 's spheres has an attraction force on . Now we use the numbers for , , , and to calculate the magnitude of electrical force on and .

We also use the numbers for , , , and to calculate the magnitude of 's electric force on .

due to two spheres and , the force on is

Because the magnitude of the force on the sphere is greater than that on the sphere , the force is directed forward.
