Answer:
The net force on the frog is zero Newton.
Explanation:
Balance forces are 2 forces that is acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an object, the object stays still or continues moving continues to move at the same speed and in the same direction
In Figure , the forces exerted on the frog is equal in magnitude and opposite in direction.
Hence
The force , F1 = 200 N and F2 = -200 N since it is acting in opposite direction
Now the net force =F1 + F2 = 200 - 200 = 0
