A solid sphere of mass \( M \) and radius \( R \) is pulled horizontally on a rough surface as shown in figure. Choose the incorrect alternatives. (1) The magnitude of the frictional force is \( F / 3 \). (2) The frictional force on the sphere acts forward. (3) The acceleration of the centre of mass is \( 2 F / 3 M \). (4) The acceleration of the centre of mass is \( F / M \). 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
