Question

what is the effect of balanced forces acting on a moving robot?
the robot will continue moving at a constant speed
the robot will accelerate
the robot will change direction
the robot will stop immediately

Explanation:

According to Newton's first law of motion, an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. When balanced forces act on a moving robot, there is no net force. So, the robot's motion state (speed and direction) remains unchanged.

Answer:

The robot will continue moving at a constant speed.
