CBSE Class 11-science Physics Illustrations of Bodies in SHM
- Two bodies P and Q of equal masses are suspended from two separate springs of constants K_{1} and K_{2} respectively. If the two bodies oscillate vertically such that their maximum velocities are equal, then what is the ratio of the amplitudes of vibration of P and Q?
- What is the frequency of oscillation of a simple pendulum mounted in a cabin that is freely falling under gravity?
- Will a pendulum gain or lose time, when taken to the top of a mountain?
- Plot a graph between the time period (T) for a simple pendulum and its length (L)?
- A graph was plotted taking log_{10}T Vs log_{10}l for a simple pendulum. What is the nature of the graph and what is its slope?
- (a) On what factors, does the energy of simple harmonically vibrating particle depend? (b) A spring of force constant k is broken into n equal parts (n>0). What will be the spring factor of each part?
- Two identical springs of force constant k each are connected in series. What will be the spring factor of the combination when they are connected in (i) Series (ii) Parallel
- A particle is vibrating in S.H.M. When the distances of the particle from the mean position are y_{1} and y_{2} it has velocities v_{1} and v_{2} respectively. Prove that the time period is,
- A tray of mass 9 kg is supported by two springs, each of force constant K as shown in the figure. On pressing the tray slightly downwards and then releasing it, it executes SHM of period 1s. When a block of mass M_{1} is placed in the tray, the period increases by 2s. Calculate the mass of the block.
- Two identical, springs each of spring factor K, may be connected in the following different ways.. Deduce the spring factor for oscillations of the body P of mass m in each case.
