980 N

Answer 1

The correct answer is 9800 N. This is because the force of gravity on an object is equal to its mass multiplied by the acceleration due to gravity. In this case, the mass of the loaded bar is 100 kg and the acceleration due to gravity is 9.8 m/s^2. Therefore, the force required to overcome the force of gravity is 100 kg * 9.8 m/s^2 = 9800 N.
