Question

what section of length is in each fluid?​

Answer 1

Answer:

L/2

Explanation:

Suppose denstiy be 'd', mass be m, area of cross section be A and volume be v.

length in upper fluid be x and lower flud be y.

so

L=x+y

Main point is

Mg=m1g+m2g

2dv=dv1+3dv2

2dAl=dAx+3dAy

2l=x+3y

Solving above eqns

x=y

So section in each fluid is L/2

I hope u get it...
