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.

Six identical particles each of mass m are arranged at the corners of a regular hexagon of side length L . If the mass of one of the particle is doubled, the shift in the centre of mass is

Six point charges are arrange at the vertices of a regular hexagon of side length a (shown in figure). Find the magnitude of electric field at the centre of regular hexagon.
