In the arrangement shown in the diagram the string is light, pulley is frictionless and the coefficient of
P
friction between the block \( A \) and the inclined plane is 0.5 . The maximum mass of the block \( B \) so that the block \( B \) does not accelerate downwards is \( \left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right) \)
W
(1) \( 10 \mathrm{~kg} \)
(2) \( 8 \mathrm{~kg} \)
(3) \( 15 \mathrm{~kg} \)
(4) \( 2 \mathrm{~kg} \)
