Question

Do each question separately and show step by step

Two spherical objects are separated by a distance of 2.80 mm. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons, As a result, each object experiences an electrostatic force that has a magnitude of 1.44 times 10^-25 N. How many electrons did it take to produce the charge on one of the objects? Two very small spheres are initially neutral and separated by a distance of 0.45 m. Suppose that 2.0 times 10^13 electrons are removed from one sphere and placed on the other, What is the electrostatic force that acts on each sphere? State whether this force is attractive or repulsive. Two tiny conducting spheres are identical and carry charges of -16 mu C and +28 mu C. They are separated by a distance of 4.0 cm. (a) What is the force that each sphere experiences? State whether this force is attractive or repulsive (b) The spheres are brought into contact, and the charges on the two spheres equalize. they are then separated to a distance of 4.0 cm. What is the force that each sphere now experiences? State whether this force is attractive or repulsive.
