(graph are schematic and not drawn to scale)
(graph are schematic and not drawn to scale)
Question 3
A mass M, attached to a horizontal spring, executes SHM with amplitude A1. When the mass M passes through its mean position then a smaller mass m is placed over it and both of them move together with amplitude A2. The ratio of 
is
isQuestion 4
The length of a simple pendulum executing simple harmonic motion is increased by 21%. The percentage increase in the time period of the pendulum of increased length is
Question 5
A mass M is suspended from a spring of negligible mass. The spring is pulled is a little and then released so that the mass executes simple harmonic oscillations with a time-period T. If the mass is increased by m, then the time period becomes
