Per NCERT §6.2 (continuous body), the CM of a continuous distribution is given by which integral?
AR = ∫ dm / M only
BR = ∫ r dm only
CR = (1/M) ∫ r dm
DR = M ∫ r dm
Answer & Solution
Correct answer: C. R = (1/M) ∫ r dm
NCERT §6.2: R_cm = (1/M) ∫ r dm, where dm is the mass element. Generalisation of discrete sum.
