Six point masses of mass m each are at the vertices of a regular hexagon of side l. Calculate the force on any of the masses.

Calculate the formula mass of CHCl3

(n-1) equal point masses each of mass m are placed at the vertices of a regular n-polygon. The vacant vertex has a position vector veca with respect to the center of the polygon. Find the position vector of centre of mass.

Calculate the formula mass of KHCO3.

Calculate the molar mass of limestone.

Three particles, each of mass 'm' are situated at the vertices of an equilateral triangle of side 'a'. the only force acting on the particles are their mutual gravitatinoal foces. It is desired that each particle move on a circle, while maintaining the original mutual separation 'a'. Find the initial velocity that should be given to each particle and also the time period of the circular motion.
