Options
- Al and 2
- B2 and 3
- C2 and 4
- D1 and 4
Correct answer
B. 2 and 3
Step-by-step solution
Things float on the principle of Archimedes’ principle When an object floats on a liquid the buoyant force that acts on the object is equal to the weight of the object. • If the weight of the object is less than the upthrust, then the object will float on the fluid. • If the weight of the object is greater than the upthrust, then the object will sink in the fluid. • If the weight of the object is equal to the upthrust, then the object will float with half of its body immersed.
