Q1. Damping is negligible for a 0.139 kg mass hanging from a light 7.00 N/m spring. The system is driven by a force oscillating with amplitude of 1.88 N. At what frequency will the force make the mass vibrate with amplitude of 0.430 m? There are two probable solutions, enter one of them.

Q2. A bead with a mass of 0.083 g and a charge of 15 nC is free to slide on a vertical rod. At the base of the rod is a fixed 10nC charge.

In stability, at what height above the fixed charge does the bead rest?
