A block of mass $m$ is suspended from a spring and executes vertical SHM of period $T$ (Figure 5.120). The amplitude is $A$ and the spring is never compressed during the oscillation. The magnitude of the minimum force exerted by the spring on the block is:

Options:

Answer:

Solution:

At the top of the motion the net force is $m ω^{2} A$ downward, so $m g - F_{min} = m ω^{2} A$ and $F_{min} = m g - \frac{4 π ^{2}}{T ^{2}} m A$ .
