Dear pallavi


This is a problem of dimention


let


V = k λadbgc


 


  where k ,a,b,c are constant


Now write the dimension of all the quantities


[ M0 L1 T-1]  = [L1]a[ M1 L-3]b [L1 T-2]c


[ M0 L1 T-1]  = [ Mb L-3b+a+c  T-2c]


compair


b=0


-2c=-1   or c=1/2


and  -3b +a+c =1


 a =1/2


so V =k(λg)1/2
