Question

When a pair of balanced forces acts on an object, the net force that results is

greater in size than both forces combined
equal in size to one of the forces
greater in size than one of the forces
equal to zero

Answer 1

Equal to zero

Explanation:

When two forces working on an object aren't equal in size, we are saying that they're unbalanced forces. The general force working on the thing is named the resultant force. If the forces are balanced, the resultant force is zero.

The pair of balanced forces acts on an object, this provides always net force working on the thing is zero.

When internet force is zero, the forces on an object are balanced. If two forces are within the same direction, they cancel one another out. Any time the forces are unbalanced, an object will remain at rest.

Consistent with Newton's first law of motion, an object at rest will occupy rest until a net force acts upon it.
