5.A fluid container is containing a liquid of density is ρ accelerating upward with the acceleration an along the inclined plane of inclination as shown  α .Then the angle of inclination  θ  of the free surface is:

Dear Student,

net downward force on the liquid along the plane is =mgsinα+manet force perpendicular to the plane =mgcosαtanθ=mgsinα+mamgcosα=gsinα+agcosαθ=tan-gsinα+agcosαoption B Regards
