Q11.A cubical block of side 0.5 m floats on water with 30% of its volume under water. What is the maximum weight that can be put on the block without fully submerging it under water? [Take, density of water = 103 kg / m3 ] JEE Main 2019 (10 Apr Shift 2) JEE Main Previous Year Paper (1) 87.5 kg (2) 65.4 kg (3) 30.1 kg (4) 46.3 kg
What This Question Tests
This problem applies Archimedes' principle to a floating block, first to find its mass, and then to calculate the additional weight it can support before becoming fully submerged.
