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...

R Two identical negative charges are placed 550. mm apart. The left object experiences a repulsive electrostatic force of 612N. A. What is the charge on each object? B. How many electrons must be removed from the left charge to make it neutral? C. In sequence the left object is touched to a third charge and then to the right charge. The left charge ends with a 2.00x104C. What was the value of the 3rd charge?

two small steel balls (5.6 g each) are separated by a distance of 5cm. If one in every billion electrons could be removed from each ball, what would be the approximate magnitude of the electrostatic force exerted by each ball on the other? (hint: steel is essentially iron, and an iron nucleus contains 26 protons and 30 neutrons.)

Two spherical objects are separated by a distance of 1.01 × 10-3 m. 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 1.83 × 10-20 N. How many electrons did it take to produce the charge on one of the objects?
