Consider a uniform cubical box of side a on a rough floor that is to be moved by applying minimum possible force F at a point b above its centre of mass (see figure). If the coefficient of friction is , the maximum possible value of for box npt to topple before moving is
Three point particles of masses 1.0 kg, 1.5 kg and 2.5 kg are placed at three corners of a right triangle of sides 4.0 cm, 3.0 cm, and 5.0 cm as shown in the figure. The centre of mass of the system is at a point:
The coordinates of centre of mass of a uniform flag shaped lamina (thin flat plate) of mass . (The coordinates of the same are shown in the figure) are :
