Vedclass · Answer

(C) The motion of the centre of mass of a body is determined by the net external force acting on it,according to Newton's second law,$F_{ext} = Ma_{cm}$.For the yo-yo to move to the right,the horizontal component of the applied force must be directed towards the right.$1$. Force $F_1$ is applied horizontally to the right. Therefore,when $F_1$ is applied,the net force on the yo-yo is to the right,causing the centre of mass to move to the right.$2$. Force $F_3$ is applied vertically upwards. It has no horizontal component,so it will not cause the centre of mass to move horizontally.$3$. Force $F_2$ is applied at an angle such that its horizontal component is directed towards the right. Therefore,when $F_2$ is applied,the centre of mass will also move to the right.Comparing the options,option $C$ is a correct statement.

$A$ yo-yo is resting on a rough horizontal table. Forces $F_1, F_2$ and $F_3$ are applied separately as shown. The correct statement is
