Question

Find the force that must be applied at D to make the resultant force a balanced force on given object .
A 20N ➡ ⬅ 10N C

B 40N ➡ ⬅ ? D

Answer 1

Any two forces acting on each other, which are not equal and opposite ( thereby causing motion ) are unbalanced forces. For example, when you push a wall with a force, neither you nor the wall moves. The wall applies an equal amount of force in the opposite direction. This is an example of balanced force.
