Statement-1 : If at t = 0, centre of mass of an isolated system is at (0, 1, 2) than at t = 2 h, 25 min, its centre of mass may be at (0, 1, 2).
Statement-2 : If external force is zero, velocity of the centre of mass is constant.
Options:
Answer:
B
Solution:
Statement-1 is true: for an isolated system is constant, and if it is zero the centre of mass may remain at (0, 1, 2).
Statement-2 is true but only states the general principle; it does not explain the specific case. Option (B).
