Question 354: Oscillations

Question

The damping force of an oscillator is directly proportional to the velocity. The unit of constant of proportionality is

Accepted Answer

Given, damping force $$\propto$$ velocity
$$\begin{aligned}
& F \propto v \
& F=k v
\end{aligned}$$
$$\begin{aligned}
&	ext { where, } k 	ext { is the proportionality constant. }\
&\Rightarrow \quad k=\frac{F}{v}=\frac{\mathrm{kg}-\mathrm{m} / \mathrm{s}^2}{\mathrm{~m} / \mathrm{s}}=\frac{\mathrm{kg}}{\mathrm{s}}=\mathrm{kg} ~\mathrm{s}^{-1}
\end{aligned}$$

Answer

$$\mathrm{kg}~ \mathrm{ms}^{-1}$$

Answer

$$\mathrm{kg} ~\mathrm{s}^{-1}$$

Answer

$$\mathrm{kg} ~\mathrm{ms}^{-2}$$

Answer

kg-s
