Question 358: Oscillations

Question

The mass M shown in the figure below oscillates in simple harmonic motion with amplitude A. The amplitude of the point P is

Accepted Answer

Since the restoring force is same in both springs (which are being in series), we have
$${k_1}{x_1} = {k_2}{x_2}$$
It is given that
$${x_1} + {x_2} = A$$
$$ \Rightarrow {x_1} = {{A{k_2}} \over {{k_1} + {k_2}}}$$

Answer

$${{{k_1}A} \over {{k_2}}}$$

Answer

$${{{k_2}A} \over {{k_1}}}$$

Answer

$${{{k_1}A} \over {{k_1} + {k_2}}}$$

Answer

$${{{k_2}A} \over {{k_1} + {k_2}}}$$
