What will be the value of the correct resulting force in the beam?

Statement (I): Emission of sulphur dioxide (SO² ) has cooling effect on atmosphere.

Statement (II): Aerosols are formed due to reaction of sulphur dioxide (SO² ) with water and oxygen in the air which reflect sunlight back into space.

Assertion: Positive pressure gradient helps in separating the boundary layer.

Reason: At the point of boundary layer separation, the shear stress is zero.
