Question

Two equal forces are applied to a door. The first force is applied at the midpoint of the door: the second force is applied at the doorknob. Both forces are applied perpendicular to the door. Which force exerts the greater torque? the first at the midpoint both exert equal non-zero torques both exert zero torques the second at the doorknob Consider a rigid body that is rotating. Which of the following is an accurate statement? Its center of rotation is at rest, i.e., not moving. All points on the body are moving with the same linear velocity. Its center of rotation is its center of gravity. All points on the body are moving with the same angular velocity.

Explanation / Answer

1) As we know torque, = F x r

Torque is directly proportional to the distance of application of force.

So, when distance of application of force is more then the torque is more.

Hence, option (d).
