A mass M at rest is broken into two pieces having masses m and (M-m). The two masses are then separated by a distance r. The gravitational force between them will be the maximum when the ratio of the masses [m: (M-m)] of the two parts is

A free particle of mass m was in motion along the x-axis on a horizontal x-y plane kept at a fixed height above the earth. On sudden explosion, the particle broke up into two pieces of masses (m)/(4) and (3m)/(4) . After an interval of time, position of the smaller fragment along y-axis become y = 15 cm. At that moment, position of the larger piece was
