If two loquid lf equal mass and different densities are mixed then

Density = 2 *d1 *d2/(d1 +d2)

= 8/3 kg/m³

Dear student

See the explanation here.

The masses of two liquids are equal, let it be m.

Let the relative densities of water and liquid be ρ1 and ρ2 respectively.

The volume of the two be V1 and V2, of water and liquid respectively.

The volume of the mixture would be, V = V1 + V2 (1)

also, volume = mass/density

thus,

2m/ρ (V) = m/ρ1 (V 1 ) + m/ρ2 (V 2 )

here ρ1 = 1, ρ2 = 2 and ρ is the relative density of the mixture.

now,

2/ρ = 1/ρ1 + 1/ρ2

by substituting the values, we

ρ/2 = 2/3

or, the relative density of the combined liquid will be, ρ= 4/3

Dear student

The ans of the above question will be 8/3 , it is by mistake written as 4/3.

Hope you will understand the explanation.

Good Luck

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
