Buoyancy depends upon mainly 2 factors
- Density of Liquid
- Volume of Solid Immersed in it
Density of Liquid
More denser the liquid, more will be buoyant force
Example
Sea Water has more buoyancy than Fresh water of rivers and swimming pool
This is because sea water has more density(It contains lots of salts which increases its density)
Volume of Solid Immersed in it
Buoyant force increases if we increase volume of solid immersed in water
If we immerse some only part of solid in water,it will show less buoyancy
If we increase solid immersed,it will show more buoyancy
