Question

In a system of units if force, accelration, and time are chosen as fundamental units,then the dimensional formula of angular momentum will bee

Answer 1

F = [MLT⁻²]

A = [LT⁻²]

L = I.ω = [ML²][T⁻¹] = [ML²T⁻¹] = [MLT⁻¹.L]

multiplying and dividing T to obtain the dimension of force

= [MLT⁻¹.T⁻¹.T.L] = [MLT⁻².T.L]

multiplying and dividing T² to obtain the dimension of acceleration

= [MLT⁻².T.L.T⁻².T²] = [MLT⁻².L.T⁻².T³] = [ F A T³ ]
