A small bead of mass 4.00 g is attached to a horizontal string. Transverse waves of amplitude A = 0.800 cm and frequency f = 20.0 Hz are set up on the string. Assume the mass of the bead is small enough that the bead doesn’t alter the wave motion. During the wave motion, what is the maximum vertical force that the string exerts on the bead?
