The damping force acting on an oscillating body is proportional to its velocity i.e. F = Kv. What is the dimensional formula for K?A. `[M^(1)L^(1)T^(-1)]`B. `[M^(1)L^(0)T^(-1)]`C. `[M^(0)L^(1)T^(-2)]`D. `[M^(1)L^(0)T^(1)]`

Answer» Correct Answer - b
`because F=KvorK=(F)/(v)`
`therefore [K]=[(F)/(v)]=[(M^(1)L^(1)T^(-2))/(L^(1)T^(-1))]=[M^(1)L^(0)T^(-1)]`
