To calculate the buoyant force on a submerged cube with a volume of 0.78 m3 and a mass of 328 kg, Archimedes' Principle is applied. The buoyant force is equal to the weight of the fluid displaced by the cube, which can be determined using the formula: buoyant force = volume of fluid displaced × density of fluid × gravitational acceleration. The weight of the cube is also relevant, as it helps in understanding the net forces acting on the object. The discussion emphasizes the importance of understanding these fundamental principles in solving buoyancy-related problems. Proper application of these concepts is essential for accurate calculations in physics.

Homework Statement
A cube, with a volume of 0.78 m3 is submerged in a swimming pool. What is the buoyant force acting on the object if it has a mass of 328 kg?
Kindly see the attached pdf. My attempt to solve it, is in it.
I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction.
I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook.
Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water.
I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
