When a drop is split into large number of drops the change in the total potential energy of small drops and potential energy of bigger drop is zero , positive , or negative ???

Answer»

It should be positive because it has some mass=m ,height=h and WHENE a body goes upward then its G= -9.8 m/s^2 but whene an body come to GROUND its g= 9.8
(extra)but whene the drop is falling on ground the three force acting on it these are f=mg and TWO force against the gravity these are upthrust force and viscous force hope you understand
