Answer:
Option B
Explanation:
In damped SHM, damping force is proportional to the velocity of the oscillator
i.e, $F_{d}\propto v=F_{d}=bv$
where, b is a damping constant
$\therefore$ Damping constant , b$=\frac{F_{d}}{v}$
SI unit of damoing constant
b= SI unit of force / SI unit of velocity $=\frac{kg.m.s^{-2}}{m.s^{-1}}$
= kg. s-1= kg/s
