Three point masses $m_1, m_2$ and $m_3$ are placed at the corners of a thin massless rectangular sheet ($1.2 \,m \times$ $1.0 \,m$ ) as shown. Centre of mass will be located at the point ........... $m$
$(0.8,0.6)$
$(0.6,0.8)$
$(0.4,0.4)$
$(0.5,0.6)$
Write short note on centre of Gravity.
A narrow but tall cabin is falling freely near the earth's surface. Inside the cabin, two small stones $A$ and $B$ are released from rest (relative to the cabin). Initially $A$ is much above the centre of mass and $B$ much below the centre of mass of the cabin. A close observation of the motion of $A$ and $B$ will reveal that
Find the centre of mass of a triangular lamina.
In the figure shown $ABC$ is a uniform wire . If centre of mass of wire lies vertically below point $A$ , then $\frac{{BC}}{{AB}}$ is close to
Mention the position of centre of mass of particles of equal mass.
