Mass is distributed uniformly over a thin square plate. If two end points of diagonal are $(-2, 0)$ and $(2, 2)$, what are the coordinates of centre of mass of plate ?
$(2, 1)$
$(2, 2)$
$(1, 0)$
$(0, 1)$
When does a body (system) have different centre of gravity and centre of mass ?
Obtain an expression for the position vector of centre of mass of a system n particles in two dimension.
Write short note on centre of Gravity.
In general form what are the coordinates of centre of mass of a rigid body.
Consider a two particle system with particles having masses $m_1$ and $m_2$. If the first particle is pushed towards the center of mass through a distance $d$, by what distance should the second particle is moved, so as to keep the centre of mass at the same position?
