A particle of mass 4m is placed 0.91 meter from a particle of mass m.
(a) Determine where should you put a third mass M so that the net gravitational force on M due to the two masses is exactly zero?
m
(b) Is the equilibrium of M at this point stable or unstable in the following situations?
(i) For points along the line connecting m and 4m
Stable or unstable
(ii) For points along the line passing through M and perpendicular to the line connecting m and 4m
Stable or unstable
