A large spherical mass M is fixed at one position and two identical point masses m are kept on a line passing through the centre of M (see figure). The point masses are connected by a rigid massless rod of length l and this assembly is free to move along the line connecting them. All three masses interact only through their mutual gravitational interaction. When the point mass nearer to M is at a distance r = 3l from M and tension in the rod is zero then the acceleration of point mass will be

Refer to the given paragraph.
The two main types of root are X and Y. X roots are mostly found in plants having leaves with reticulate venation, while Y roots are mostly found in plants having leaves with parallel venation.
Select the incorrect statement regarding X and Y.

A Radish, turnip and carrot are modifications of X.
B X is found in gram while Y is found in barley.
C X spreads horizontally hence cannot provide strong anchorage whereas Y penetrates very deep into the soil hence provides strong anchorage.
D In Y, primary root is short-lived while X has persistent primary root.
