Question1

Two blocks are associated by a light string that passes over a frictionless pulley. The block of mass m1 lies on a horizontal surface and is associated to a spring of force constant k. The system is released from rest while the spring is unstretched. If the hanging block of mass m2 falls the distance h before coming to rest, compute coefficient of kinetic friction between block of mass m1 and surface.

Question2

A small sphere of mass m = 7.30 g and charge q1 = 28.7 nC is attached to the end of a string and hangs vertically as in the figure. A second charge of equal mass and charge q2 = -58.0 nC is located below the first charge a distance d = 2.00 cm below first charge as in the figure. Find out the tension of the string.

Question3

Two identical strings are sounding the similar fundamental tone of frequency 156 Hz. Each string is under 233 N of tension. The peg holding one string suddenly slips, tumbling its tension slightly, and the two tones now produce a beat frequency of three beats per second. What is new tension in the string that slipped?
