Questions
A small metal sphere falls down in a liquid with terminal velocity when the viscous force on it and its weight are in the ratio 2:5. Then the density of the sphere is
detailed solution
Correct option is B
condition for terminal velocity W= Fb+Fv here buoyant force Fb= W-Fv so Fb= 5F-2F =3F W= Vdsg =5F and Fb=Vdlg=3F ds=53dlTalk to our academic expert!
