Question

The damping force on a oscillator is directly proportional to the velocity. The Unit of the constant of proportionality are:

• A. kgs${}^{-1}$
• B. kgs
• C. kgms${}^{-2}$
• D. kgms

Answer 1

Answer: (A)

kgs${}^{-1}$

$F=Kv$
$K=\frac{F}{V}$
Unit of K = $K=\frac{kgm{s}^{-2}}{m{s}^{-1}}=kg{s}^{-1}$
