If m' is the mass of a body, 'a' is amplitudeof vibration, and 'ω' is the angularfrequency, ma has same dimensionalityformula asl) impulse 2) moment of momentum3) moment of inertia 4) moment of force

Answer»

dimension of 1/2*m*(aw)² = ML²T-² = M(L/T)² = ML²/T² = (MLT-²)L = F×d = moment of force

option 4
