The damping force on an oscillator is directly proportional to the velocity. The units of the constant of proportionality are:
Kgms-1
Kgms-2
Kgs-1
Kgs
As we discussed in

This option is incorrect.
Option 2)
Kgms-2
This option is incorrect.
Option 3)
Kgs-1
This option is correct.
Option 4)
Kgs
This option is incorrect.
