Answer:
It will not change
Explanation:
The period of oscillation of a mass-spring system is given by
where
T is the period
m is the mass hanging on the spring
k is the spring constant
As we see from the formula, the period of oscillation does not depend on the amplitude of the motion: therefore, if we change the amplitude, the time for one oscillation will not change.
Answer:
(c) 4M
Explanation:
The system is a loaded spring. The period of a loaded spring is given by
<em>m</em> is the mass and <em>k</em> is the spring constant.
It follows that, since <em>k</em> is constant,
where <em>C</em> represents a constant.
When the period is doubled, .
Hence, the mass is replaced by 4M.
