Directions: Study the following line chart carefully and answer the questions given beside.
The following Graph shows the ratio values of a mixture of Propane and Butane in 5 vessels A, B, C, D, E.
(For example, the Ratio of Propane and Butane in vessel A is 30 : 12)
In what ratio must mixture in the vessel C and D be mixed to get the final ratio 115: 81 of Propane and Butane?
Magnetic flux-
The total number of magnetic lines of force passing normally through an area placed in a magnetic field is equal to
the magnetic flux linked with that area.
I.e for the below figure
Net magnetic flux through the surface is given by
