AIEEE 2003 A mass$$M$$is suspended from a spring of negligible mass. The spring is pulled a little and then released so that the mass executes$$SHM$$of time ... AIEEE 2003 Two particles$$A$$and$$B$$of equal masses are suspended from two massless springs of spring of spring constant$${k_1}$$and$${k_2}$$, respectiv... AIEEE 2003 The length of a simple pendulum executing simple harmonic motion is increased by$$21\% $$. The percentage increase in the time period of the pendulum... AIEEE 2003 A body executes simple harmonic motion. The potential energy$$(P.E),$$the kinetic energy$$(K.E)$$and total energy$$(T.E)$$are measured as a func... AIEEE 2003 The displacement of particle varies according to the relation$$x=4\left( {\cos \,\pi t + \sin \,\pi t} \right).$$The amplitude of the particle ... AIEEE 2002 If a spring has time period$$T,$$and is cut into$$n$\$ equal parts, then the time period of each part will be
