torque due to action and reaction is not zero?true or false
True. Torque due to action and reaction is not zero.
To understand why, let's first define torque. Torque is the measure of the turning force around an axis or pivot point. It is given by the product of the force applied and the perpendicular distance from the axis of rotation to the line of action of the force.
Now, when two objects interact with each other, they exert equal and opposite forces on each other as per Newton's third law of motion. These forces are known as action and reaction forces.
However, while the action and reaction forces are equal and opposite, their torques can be different. This is because torque also depends on the perpendicular distance from the axis of rotation to the line of action of the force. If the distances are different, the torques will be different.
For example, consider a seesaw or a teeter-totter where two people sit on opposite ends. Even though the forces they exert on the seesaw are equal and opposite, the torques they create are different because the distances to the pivot point are different. This results in a net torque and causes the seesaw to rotate.
Therefore, torque due to action and reaction is not zero because the torques depend on the distances from the axis of rotation to the line of action of the forces.
