The damping force on an oscillator is directly proportional to the velocity.

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

Options

(a) kgms⁻¹
(b) kgms⁻²
(c) kgs⁻¹
(d) kgs

Correct Answer:

kgs⁻¹

Explanation:

F ∞ v ⇒ F = kv
k = F / v ⇒ [k] = [kgms⁻²] / [ms⁻¹]
= kgs⁻¹
