Per NCERT §6.4, the total LINEAR MOMENTUM of a system of particles equals which?
ASum of internal momenta only
BAlways zero
CM V_cm (total mass times CM velocity)
DEqual to total angular momentum
Answer & Solution
Correct answer: C. M V_cm (total mass times CM velocity)
NCERT §6.4: P_total = Σ m_i v_i = M V_cm. Useful because the motion of CM captures total momentum.
