Q. The mass of an electron is 9 x 10-31 kg. The mass of a proton is 1.7 x 10-27 kg. The proton and electron are about 1.0 x 10-10 m apart in a hydrogen atom. What force of gravitation exists between the proton and the electron of a hydrogen atom? What is the centripetal acceleration of the electron?

Q. Learning Goal: To practice Problem-Solving Strategy 21.1 Coulomb's Law.

Three charged particles are placed at each of three corners of an equilateral triangle whose sides are of length 2.8 . Two of the particles have a negative charge: = -6.7 and = -13.4 . The remaining particle has a positive charge, = 8.0 . What is the net electric force acting on particle 3 due to particle 1 and particle 2?
