Friction on horizontal surface

Question

A block weighing 10kg is at rest on a horizontal table. The coefficient of static friction between the block and the table is 0.5. If a force acts downward at 60º with the horizontal, how large can it be without causing the block to move? (g = 10ms^–2)

Moderate

A

346 N
B

446 N
C

746 N
D

846 N

Solution

$Fcos θ = f, f = μ_{s} N, N = mg + Fsin θ$
