The critical velocity v of a body depends on the coefficient of viscos

1.	The critical velocity v of a body depends on the coefficient of viscosity eta the density d and radius of the drop r. If K is a dimensionless constant then v is equal to
Answer» `(K eta d)/(R )` `(Kd)/(eta r)` `(K eta)/(dr)` `(KR)/(eta r)` ANSWER :C
