QUESTION:
A balloon that weighs 1 N is suspended in air, drifting neither up nor down. (a) How much buoyant force acts on it? (b) What happens if the buoyant force decreases? (c) If it increases?
ANSWER:Solution Step 1 of 3 (a) How much buoyant force acts on it Since the balloon is not moving,it is at rest as in the figure above HEnce the downward weight due to gravity is balanced by the buoyant force which acts upward. Which means, the buoyant force is equal in magnitude to the weight. That is B=W Since W= 1N B= 1N Hence the buoyant force on the balloon is 1 N.
