A simple pendulum of length 100 cm performs S.H.M. Find the restoring force acting on its bob of mass 50 g when the displacement from the mean position is 3 cm.
The data that we can put forward from this question is , Length L= 100cm …
Potential energy of a particle performing linear S.H.M is 0.1 π² x² joule. If mass of the particle is 20 g, find the frequency of S.H.M.
The data available in the sums is, Joule mass m = 20g = 0.020kg To find …
The total energy of a body of mass 2 kg performing S.H.M. is 40 J. Find its speed while crossing the centre of the path.
The given data from the question can be listed as, mass m = 2kg Total Ener…
