Question

What happens to the velocity of an object when balanced forces act on it?

Answer 1

Hints:
Balanced force means the resultant of the forces equals zero.
Then apply Newton's first law:
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
