Two men of masses M and (M + m) climb a massless and inextensible rope from either end over a hanging pulley, from the same ground level with different uniform accelerations starting at the same instant. If the acceleration of the lighter man is 'g' units, greater than twice the acceleration of the heavier man, then m is equal to (take `g = 10 ms^(-2)`)

Options

A. M/2
B. M
C. 2/3 m
D. 3/4 m

Answer

B
