(b)

P =  Þ Pbx = a – t2 ® [Pbx] = [a] = [T2]
Or [b] =  = [M–1T4]
= [MT–2]

[a]=[t2]=T2 
[P]=T2/[bx]
[b]=T2/[P][x]=T2/ML-1T-2L=M-1T4
a/b=T2/M-1T4=MT-2
Thanks And Regards

Dear Student,
Please find below the solution to your problem.

[a]=[t2]=T2
[P]=T2/[bx]
[b]=T2/[P][x]=T2/ML-1T-2L=M-1T4
a/b=T2/M-1T4=MT-2

Thanks and Regards
