A particle of mass \(5 \mathrm{~g}\) is executing S.H.M. with an amplitude \(0.3 \mathrm{~m}\) and period \(\frac{\pi}{5} \mathrm{~s}\). The maximum value of the force acting on the particle is

  1. A \(0.15 \mathrm{~N}\)
  2. B \(4 \mathrm{~N}\)
  3. C \(5 \mathrm{~N}\)
  4. D \(0.3 \mathrm{~N}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(0.15 \mathrm{~N}\)

Step-by-step Solution

Detailed explanation

\(
\begin{aligned}
& \mathrm{m}=5 \mathrm{~g}=5 \times 10^{-3} \mathrm{~kg}, \mathrm{~A}=0.3 \mathrm{~m}, \mathrm{~T}=\frac{\pi}{5} \mathrm{~s} \\
& \omega=\frac{2 \pi}{\mathrm{T}}=10 \mathrm{rad} / \mathrm{s}
\end{aligned}
\)
Maximum force, \(\mathrm{F}=\mathrm{m} \omega^2 \mathrm{~A}=5 \times 10^{-3} \times(10)^2 \times 0.3=0.15 \mathrm{~N}\)
