Question

The figure shows a steel ball suspended in water by a springscale. W is the weight of the ball in air, FB is thebuoyant force on the ball, and Fs is the reading on thespring scale (apparent weight). The density of steel is greaterthan the density of water. For each of the following statementschoose the correct option. less than greater to , equal than or true or false The weight, W, of the ball is ............ the reading onthe scale , Fs.
................. If the string attached to the ball is removed,the ball will sink to the bottom.
• The buoyant force, FB is .............weight of the water displaced by the ball.
• The weight, W, of the ball is ............. themagnitude of sum of Fs and FB.
• The buoyant force, FB, on the ballis .............. the weight, W, of the ball.

Explanation / Answer

       From the diagram andNewtons law                      Fs + Fb = W (mg)              so The weight, W, of the ball is greater the reading on the scale ,Fs. If the string attached to the ball is removed, the ballwill sink to the bottom ( true)   The buoyant force, FBis equal weight of the waterdisplaced by the ball.
• The weight, W, of the ball is equal to the magnitude of sum of Fs andFB.
• The buoyant force, FB, on the ballis Less than the weight, W, ofthe ball.
