Question
Two spheres of same size, one of mass 2kg and other of 20kg are dropped simultaneously from the top of Qutub Minar (height = 72m). When they are 1m above the ground the two spheres have the same:
Options
A.momentum
B.kinetic engry
C.potential engry
D.acceleration
Solution
Since their masses are different they will have different moment, kinetic energy and potentil energy. But their acceleration will be same which will be equal to g.
