    Gravitation. Asked once: 2021 Paper 20 (same type asked 4 times) See all 4 of this type

    21
    A body of mass (2M) splits into four masses {m,M−m,m,M−m}\mathbf{\{ m,M - m,m,M - m\}}, which are rearranged to form a square as shown in the figure. The ratio of Mm\frac{M}{m} for which, the gravitational potential energy of the system becomes maximum is x:1x:1. The value of xx is.
