Two stones of different masses are dropped simultaneously from the top of a building (a)Smaller stone reaches the ground earlier (b)Larger stone reaches the ground earlier (c)Both the stones reach the ground at the same time
option C . Both stones attain the floor on the identical time. The preliminary pace is zero for each stones, and the handiest acceleration operating in that gadget might be g (Gravity acceleration). So, as the gap is the identical, the very last velocity might be the equal time. The most effective cause that can extrade this end result is a distinction withinside the form of the stones. While they fall to the floor, they must “open” a manner throughout the air. The form of the falling item will determine the pressure had to open that manner. This is referred to as the “Air resistance”. Depending at the form of the item, the resistance pressure may be larger or smaller. As this pressure works counter to g, the falling time will decrease. Between a feather and a plumb ball, the falling time can be the identical in vacuum, however interior air, the resistance pressure for the feather has nearly the identical fee than gravity, whilst for the ball, the resistance may be very plenty weaker than gravity.
