1) Assume that you have two objects one with a mass of 10 kg and the other with a mass of 15 kg each with a charge of +3.0x10^-6 C and separated by a distance of 2 m. What is the electric force that these objects exert on one another?

2) Determine what happens to the electric force in the following:
a) The distance between the objects doubles.
b) the charge on two identical objects doubles.
c) the charge on two identical objects doubles and the distance between the object doubles?

please help me!!

Sure, I'd be happy to help explain how to solve these problems!

1) To find the electric force exerted between two charged objects, you can use Coulomb's law. Coulomb's law states that the electric force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

The formula for Coulomb's law is:

F = k * (q1 * q2) / r^2

Where F is the electric force, k is the electrostatic constant (9.0 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the two objects, and r is the distance between them.

In this case, the charges of the two objects are +3.0x10^-6 C each, and the distance between them is 2 m. Plugging these values into the formula, we get:

F = (9.0 x 10^9 Nm^2/C^2) * ((3.0x10^-6 C)^2) / (2m)^2

Simplifying this expression, we have:

F = (9.0 x 10^9 Nm^2/C^2) * (9.0x10^-12 C^2) / 4 m^2

Calculating this expression, we find:

F = 2.025 N

Therefore, the electric force that these objects exert on each other is 2.025 Newtons.

2) Now let's consider the scenarios mentioned:

a) If the distance between the objects doubles, according to Coulomb's law, the electric force between the objects will decrease. Since the force is inversely proportional to the square of the distance, doubling the distance will result in a fourth (1/2^2) of the original force.

b) If the charge on two identical objects doubles, the electric force between them will also double. This is because the force is directly proportional to the product of their charges. Doubling the charge will result in double the force.

c) If both the charge on two identical objects and the distance between them double, we can calculate the effects separately. Doubling the charge will double the force, as explained in scenario b. Doubling the distance will reduce the force to a quarter, as explained in scenario a. Therefore, the net effect will be that the force will be half (doubled charge) times a quarter (doubled distance), resulting in one-eighth of the original force.

I hope this helps! Let me know if you have any further questions.
