A cylinder of radius r floats vertically in a liquid of density p. The surface tension of the liquid is T and the angle of contact between cylinder and liquid is 30°. If a second substance is added, making the angle of contact 90°, which one of the following statements is correct? O The cylinder floats higher by a distance h given by r²hpg = 2πT O The cylinder floats deeper by a distance h given by r²hpg = 2πrT cos 30⁰ O The depth to which the cylinder is submerged is unchanged. O The cylinder floats deeper by a distance h given by hps = Σπιτ The cylinder sinks to the bottom. O The cylinder floats higher by a distance h given by r²hpg = 2πT cos 30º
