1.	In which of the following cases the net force is zero .A. a drop of rain falling down with terminal velocityB. a cork of mass `20g` floating in waterC. a car moving with constant speed of `60km//h` on a rough roadD. in a tug of war game if one team applies more force than other
Answer» Correct Answer - a,b,c If a rain drop falls with terminal velocity weight = upthrust + viscous drog `:. F _("net") = 0` For a cork floating in water weight = upthrust `:. F_("net") =0` In case of constant speed of a car, `a =0` In a tug of war game if one team applies more force than other then net force will be the resultant of two forces Which will not be zero `F _("net") ne 0` .
