Explanation Given: Mass of cheerleader, m = 55 kg Mass of all football players, M = 110 kg Height of piston from the ground, h = 1.0 m Diameter of cheerleader piston, d c = 16 cm Formula used: The pressure is stated as the ratio of the force applied on the piston to the cross-sectional area of the piston as given below: P = F A Here, P is the pressure, F is the force and A is the area of the cross-section. The pressure under both the piston must be the same because the cheerleader and four football players at the same height from the ground is: P 1 = P 2 + ρ g h F 1 A 1 = 4 F 2 A 2 + ρ g h m g π ( d 2 ) 2 = 4 M g π ( d f 2 ) 2 + ρ g h Here, m is the mass of the cheerleader, M is the mass of all the four football players, g is the acceleration due to gravity, d f is the diameter of the piston on which football players’ are standing and d is the diameter of the piston on which cheerleader is standing and ρ is the density of the oil
