Q. The damping force on an oscillator is directly proportional to the velocity. The units of the constant of proportionality are
A) kg s
B) kg m s⁻¹
C) kg m s⁻²
D) kg s⁻¹
Explanation
[Solution from source] F = bv, so b = F/v with units (kg m s⁻²)/(m s⁻¹) = kg s⁻¹. kg m s⁻² is the unit of force itself, not of the constant. Answer (4).
