A block of mass 50 kg can slide on a rough horizontal surface. The coefficient of friction between the block and the surface is 0.6. The least force of pull acting at an angle of 30° to the upward drawn vertical which causes the block to just slide is

Answer: (D)

Solution

Taking θ = 30° from the vertical (so the horizontal component is Fsin30° and the vertical, upward, component is Fcos30°): the block just
