A cubical block of side 0.5m floats on water with 30% of its volume...
A cubical block of side floats on water with 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 ]
[Take, density of water ]
Options
- A
- B
- C
- D
Correct answer
A.
Step-by-step solution
In first case, when of the cube inside water,
Additional weight we can put is,
\left({ρ}_{w} - {ρ}_{c}\right)g= {\left(0.5\right)}^{3} \times 0.7 \times {10}^{3} \times g= 87.5gN= 87.5kg
Additional weight we can put is,
\left({ρ}_{w} - {ρ}_{c}\right)g= {\left(0.5\right)}^{3} \times 0.7 \times {10}^{3} \times g= 87.5gN= 87.5kg
