Question
What type of forces – balanced or unbalanced – act on a rubber ball when we press it between our hands ? What effect is produced in the ball ?
Solution
The balanced forces change the shape of the rubber ball when we squeeze it.
When we press a rubber ball between our two hands, the shape of the ball alters from spherical to oblong. This is because two equal and opposite forces (balanced force) are applied by our hands.
