A child swinging on swing in sitting position stands up.The time period of the swing will
The graph of time period (T) of simple pendulum versus its length (l) is
Which of the following is a simple harmonic motion?
A rod is hinged vertically at one end and is forced to oscillate in a vertical plane with hinged end at the top, the motion of the rod:
The graph plotted between the velocity and displacement from mean position of a particle executing SHM is
Acceleration of a particle executing SHM, at it’s mean position is
A vertical mass-spring system executes simple harmonic oscillations with a period of 2s. A quantity of this system which exhib its simple harmonic variation with a period of 1 s is
A simple pendulum has a metal bob, which is negatively charged.If it is allowed to oscillate above a positively charged metallic plate, then its time period will
A body of mass 5 gram is executing S.H.M. about a fixed point O. With an amplitude of 10 cm, its maximum velocity is 100 cm/s. Its velocity will be 50 cm s–1 at a distance(in cm)
Vmax=100=aω;ω=100/a=100/10= 10 rad/s
v2= ω2(a2 – y2) or 502
= 102(102– y2) or 25 = 100 – y2
or y=\(\sqrt{75}=5\sqrt{3}\)cm.
A pendulum is under going S.H.M. The velocity of the bob in the mean position is v. If now its amplitude is doubled,keeping the length same,its velocity in the mean position will be
Vmax=aω;V'max=2aω=2Vmax=2v
(since vmax=v)
