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 maximum when the ratio of the masses [m : (M-m) of the two parts is

Answer»

`1:1`
`1:2`
`1:3`
`1:4`

SOLUTION :Using. `F=(Gm_(1)m_(2))/(r^(2))`(Universal law of gravitation)
Here, `m_(1)=m` and `m_(2)=(M-m) :. F=G(m(M-m))/(r^(2))=0`
or `M-2m=0`
`RARR m=(M)/(2) :. (m)/((M-m))=(M//2)/((M-M//2))=(1)/(1)`
