A) \[kg\,m{{s}^{-1}}\]
B) \[kg\,m{{s}^{-2}}\]
C) \[kg\,{{s}^{-1}}\]
D) \[kg\,s\]
Correct Answer: C
Solution :
| Given, Damping force \[\propto \] velocity |
| \[F\propto v\] |
| \[F=kv\] |
| \[k=\frac{F}{v}\] |
| Unit of \[k\,=\frac{\text{unit}\,\text{of}\,F}{\text{unit}\,\text{of}\,v}\] |
| \[\,=\frac{kg-m{{s}^{-2}}}{m{{s}^{-1}}}=kg{{s}^{-1}}\] |
