The viscous force acting on a body moving through a liquid is proportional to its velocity. What is the dimensional formula for the constant of proportional to its velocity. What is the dimensional formula for the constant of proportionality?A. `[M^(1)L^(1)T^(-1)]`B. `[M^(1)L^(1)T^(-2)]`C. `[M^(1)L^(0)T^(-1)]`D. `[M^(0)L^(1)T^(-1)]` |

Answer» Correct Answer - c `Fpropv therefore F=kv or k=(F)/(v)` `therefore [k]=[(M^(1)L^(1)T^(-2))/(L^(1)T^(-1))]=[M^(1)L^(0)T^(-1)]` |
