s= [L]
ut= [LT-1 ]× [T]= [L]
1/2= constant, hence no dimension
at2= [LT-2] × [T2] =[L]
hence this equation is correct on the basis of homogeneity principle...
(ii)t = 2 pie √l/g
t= [T]
2 pie= constant , hence no dimension
√l/g= √L/LT-2 = √1/T-2 =√T2 = [T]
hence this equation is correct on the basis of homogeneity principle...
