D Question 6 A cylinder of radius r floats vertically in a liquid of density 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 depth to which the cylinder is submerged is unchanged. The cylinder floats higher by a distance h given by rh g=2 % rT 5 pts
The depth to which the cylinder is submerged is unchanged. The cylinder floats higher by a distance h given by R r²h 8=2 म rT The cylinder sinks to the bottom. O The cylinder floats deeper by a distance h given by K r²h g=2 म rT O The cylinder floats deeper by a distance h given by K r2h
Ph 8=2 rT O The cylinder floats deeper by a distance h given by 22h 8=2 rT cos 30⁰ O The cylinder floats higher by a distance h given by 2h 8=2 rT cos 30°
€ 2h k 8=2 rT O The cylinder floats deeper by a distance h given by rh 8=2 rT cos 30º O The cylinder floats higher by a distance h given by ²h 8-2 rT cos 30º
