Statement I If the centre of mass of a system is at rest, the KE of the system must be zero.
Statement II The change in velocity depends on the external force.
Text Solution
Verified by ExpertsThe correct answer is:
C
Statement I is false but the Statement II is true.
If a body at rest explodes into two parts due to internal force, then its centre of mass will be at rest but the KE of the system is non-zero.
The change in velocity, depends on the external force.
