A body floats in a liquid if the buoyant force is:
equal to its weight
The buoyant force must be equal to the weight of the body for it to float in the liquid. If the buoyant force is greater than the weight, the object will rise; if it is less, the object will sink. Thus, the correct answer is (a) equal to its weight.
