Construct a circle with centre M and radius 4 cm

Construct two circles with same Radii in such away that. i) the circles intersects at two points, ii) Touch each other at one point only.

Construct a circle with centre M and radius 10 cm.

Three uniform spheres each of mass m and radius R are kept in such a way that each touches the orher two. Find the magnitude of the gravitational force on any one of the spheres due to the other two.
