Three particles each of mass `m` are placed on the vertices of an equilateral triangle of length `L`. Find the `M.I`.
(`a`) about an axis passing through
(`i`) one particle and perpendicular to the plane
(`ii`) mid-point of the side of triangle and `bot^(ar)` to the plane
(`iii`) center of triangle and `bot^(ar)` to the plane
(`b`) (`i`) an axis coinciding with side of triangle
(`ii`) about median of triangle
A. `IV,III,II,I`
B. `III,II,IV,I`
