Sep 03, 2016 · Three identical springs A, B &C each of natural length I are connected to a point mass m as shown in the figure. A & B are horizontal and C is vertically fixed with rigid supports.
A particle of mass m is attached to a light string of length l, the other end of which is fixed. Initially the string is kept horizontal and the particle is given an upward velocity v. The particle is just able to complete a circle. (a) The string becomes slack when the particle reaches its highest point.
brought close to each other , they repel each other [Fig. 1.1(a)]. The two strands of wool or two pieces of silk cloth, with which the rods were rubbed, also repel each other . However , the glass r od and wool attracted each other . Similarly, two plastic r ods rubbed with cat’s fur repelled each other [Fig. 1.1(b)] but attracted the fur. On ...
