The magnitude of the electrostatic force between two identical ions that are separated by a distance of 7.30 × 10-10 m is 10.83 × 10-⁹ N. (a) What is the charge of each ion? (b) How many electrons are "missing" from each ion (thus giving the ion its charge imbalance)?

Block A rests on a horizontal tabletop. A light horizontal rope is attached to it and passes over a pulley, and block B is suspended from the free end of the rope. The light rope that connects the two blocks does not slip over the surface of thè pulley (radius 0.080 m) because the pulley rotates on a frictionless axle. The horizontal surface on which block A (mass 3.70 kg) moves is frictionless. The system is released from rest, and block B (mass 6.00 kg) moves Part A What is the tension force that the rope exerts on block B? downward 1.80 m in 2.00 s.

When two identical conducting spheres are held in place and their center-to-center spacing is 42.5 cm, they attract each other with an electrostatic force of 0.019 N. A tiny conductive wire connects the spheres after that. The spheres repel each other with an electrostatic force of 0.0360 N when the wire is removed. With a positive net charge, what was (a) the negative charge on one and (b) the positive charge on the other of the original charges on the spheres?

Common static electricity involves charges ranging from nanocoulombs to microcoulombs. (a) How many electrons are needed to form a charge of −4.50 nC? (b) How many electrons must be removed from a neutral object to leave a net charge of 0.410 µC?
