A string of length 10.0m has a linear mass density of 25g/m. The string is fixed at the top and has an object of mass 0.200 kg hanging from the bottom.
(a) What is the initial wave speed of a pulse sent up the string from the bottom.
(b) What is the speed of the pulse as it approaches the top of the string?
One particle has a mass of 4.41 x 10-3 kg and a charge of +6.92 ?C. A second particle has a mass of 6.52 x 10-3 kg and the same charge. The two particles are initially held in place and then released.
