The force acting on the scale is zero and the torque acting about centre of mass of the scale is also zero.
Key concept: To solve these types of problem we have to apply Newton’s second law of motion !
Newton’s Second Law of Motion.
According to this law: The rate of change of linear momentum of a body is directly proportional to the external force applied on the body and this change takes place always in the direction of the force applied.
