mass of the block is 3.5kg
so block is floats on the water then we are say density of the body less than the water
there is only along normal force acting the body
buoyant force=mass*gravity
B=3.5*9.8
B=34.8Kg/m/sec^2.
thank you
Measure how much it can lift.
yes in case of buoyant force........
Using the rough rule-of-thumb: 1 liter of water = 1 kg.-- The block sinks until it has displaced 720 liters of water. At that point,the mass of the displaced water has the same weight as the mass of theblock has, and the block sinks no further.-- The block still has 280 liters of its volume above water. If that were submerged,another 280 kg of water would be displaced.-- The additional 280 kg of water would weigh (280 x 9.8) = 2,744 newtons (617.3 pounds).That much additional buoyant force would fight the effort to submerge the block.It takes an additional 2,744 newtons (617.3 pounds) to keep the block under water.
Archimedes' Principle states that for a body immersed in a fluid it will experience a buoyant force equal to the weight of the fluid that the body displaces, buoyancy is the phenomenon of concern.
buoyant force can be expressed as: F(b) = W(air) - W(liquid) = d * g * v where d is the density of the liquid, g is the acceleration of gravity and v is the volume of the immersed object (or the immersed part of the body if it floats). In this experiment the pan balances will compare masses in grams rather than weights. Since W=mg, the apparent change in mass when submerged is m - m(apparent) = d(liquid) * v
The block of Styrofoam floats on water while a same size block of lead lies submerged in the water. The buoyant force is greatest on the lead. Compared to an empty ship, the same ship loaded with Styrofoam will float lower in the water.
buoyant force is always or equal to the force exerted by gravity. that's why an object floats.
If the object is floating, then the buoyant force is equal to the object's weight.
If the object is floating, then the buoyant force is equal to the object's weight.

An object floats when the buoyant force is equal to the object's weight. An object sinks when the buoyant force is less than the object's weight.
accelerates upward, and may shoot up out of the water.If the buoyant force is equal to the force of gravity, then the object floats right there.
If the force of gravity is greater than the buoyant force, the object will sink. If the buoyant force is greater than the force of gravity, the object will rise. If the force of gravity equals the buoyant force (neutral buoyancy), the object will float.
If it's floating, then the buoyant force on it must be 30 pounds upward.
It will accelerate upward. When it reaches the surface and part of the object sticks out of the fluid, then the buoyant force decreases. When enough of it sticks out so that the buoyant force exactly equals the force of gravity (the object's weight), then it stops rising and stays right where it is (floats).
A solid block of steel will sink because the buoyant force isn't the same as its weight.
