Suspended Steel Ball
The figure shows a steel ball suspended in water by a spring scale. W is the weight of the ball in air, FB is the buoyant force on the ball, and Fs is the reading on the spring scale (apparent weight). The density of steel is greater than the density of water. For each of the following statements choose the correct option.
The magnitude of sum of Fs and FB, is equal to the weight, W, of the ball.
The weight, W, of the ball is greater than the buoyant force, FB, on the ball
true: If the string attached to the ball is removed, the ball will sink to the bottom.
The buoyant force, FB is equal to weight of the water displaced by the ball.
The reading on the scale, Fs, is less than the weight, W, of the ball.
The magnitude of sum of Fs and FB, is equal to the weight, W, of the ball.
The weight, W, of the ball is greater than the buoyant force, FB, on the ball
true: If the string attached to the ball is removed, the ball will sink to the bottom.
The buoyant force, FB is equal to weight of the water displaced by the ball.
The reading on the scale, Fs, is less than the weight, W, of the ball.
