In the figure, a block of weight 60 N is placed on a rough surface. The coefficient of friction between the block and the surface is 0.5. The minimum weight of the block does not slip on the surface is (x xx 10) N. The value of x is

Two blocks of masses m and 3m on a horizontal surface are in contact with the ends of a horizontal massless spring. The coefficient of friction between m and surface and between 3m and surface is mu and mu//3 respectively. The two blocks are moved towards each other to compress the spring and then released. The two blocks move off in opposite directions covering distances S_(1) and S_(2) before comming to rest. S_(1):S_(2) is
