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

Options

A. `kg m s^(-1)`
B. `kg m s^(-2)`
C. `kg s^(-1)`
D. `kg s`

Answer

C

Explanation

`F_(d) prop v`
`F_(d)=-bv`
`F_(d)=kv`
`:.k=(F_(d))/(v)`
Units of `k=(kgms^(-2))/(m//s)`
`kgs^(-1)`
Units of proportionality constnat `=kgs^(-1)`
