A point particle of mass and charge is constrained to move
Chapter , Problem 81(choose chapter or problem)
A point particle of mass and charge is constrained to move vertically inside a narrow, frictionless cylinder (Figure 21-47). At the bottom of the cylinder is a point charge having the same sign as q. (a) Show that the particle whose mass is m will be in equilibrium at a height (b) Show that if the particle is displaced from its equilibrium position by a small amount and released, it will exhibit simple harmonic motion with angular frequency
