Verified Answer
A roller coaster is designed such that rider experience weightlessness...
Let a liquid of density ρ rise a height h in a capillary of radius r
And we can suppose:
hrρg = 2Tcosθ
Where T is surface tension of that liquid and θ is angle of contact and
θw is the angle of contact of water
Let Tm and Tw be the surface tension of water and mercury.
Tm/Tw = [(3.112 * 13.6)/(10 * 1)] * [cosθw / cos(1350)]
