Question

A hollow sphere of mass M and radius R is immersed in a tank of water (density ρ w ). The sphere would float if it were set free. The sphere is tied to the bottom of the tank by two wires which makes angle 45 ° with the horizontal as shown in the diagram. The tension T 1 in the wire is, 4 3 π R 3 ρ w g - M g 2, 2 3 π R 3 ρ w g - M g, 4 3 π R 3 ρ w g - M g 2, 4 3 π R 3 ρ w g + M g

MARKS App · Accepted Answer

∴ 2 T 1 + M g = 4 3 π R 3 ρ w g ∴ T 1 = 4 3 π R 3 ρ w g - M g 2
