1. In terms of time t and distance x, the force F is givenby F = Asin Ct + B cosDx, then dimensions ofare given by(a) [MLOT, MLT (b)MLT 2, MLT-(c) [MLT 2), [MLT (d) [M'LT ], [MLTandB DUK PMT 2015]

Answer»

A/B=Force/Force [M^o L^o T^o ]

ct = angle

C = angle/time=1/T=T^(-1)

Dx = angle

D = angle/distance=1/L = L–1

C/D=T^(-1)/L^(-1) =[M^o LT^(-1) ]
