A uniform thin flat isolated disc is floating in space. It has radius \( R \) and mass \( m \). A force \( F \) is applied to it at a distance \( d=(R / 2) \) from the centre in the \( y \)-direction. Treat this problem as twodimensional. Just after the force is
\( \mathrm{P} \) applied
(1) acceleration of the centre of the disc is \( F / m \)
(2) angular acceleration of the disk is \( F / m R \)
(3) acceleration of leftmost point on the disc is zero
(4) point which is instantaneously unaccelerated is the rightmost point
