A block A kept on an inclined surface just begins to slicl if the inclination is 30°.
A block A kept on an inclined surface just begins to slicl if the inclination is 30°. The block is replaced by another block B and it is found that it just begins to slide if the inclination is 40°.
(a) mass of A > mass of B
(b) mass of A < mass of B
(c) mass of A = mass of B
(d) all the three are possible

(d) all the three are possible
Explanation:
It is the case of maximum static friction. The blocks begin to slide if the coefficient of static friction µ = tanΘ, irrespective of their masses. So, all the three situations are possible.
