A block of mass 1 kg is at rest on a horizontal table. The coefficient of static friction between the block and the table is 0.5. If g = 10 ms⁻², then the magnitude of the force acting upward at an angle of 60° from the horizontal that will just start the block moving is

Answer: (B)

Solution

The force's vertical component reduces the normal reaction: N = mg − Fsin60°. At the verge of
