HARD

A block of mass 2 kg rests on a rough inclined plane making an angle of 30° with the horizontal. The coefficient of static friction between the block and plane is 0.7 and kinetic friction is 0.5. A horizontal force F is applied to the block. The minimum value of F required to move the block up the incline is closest to (Take g = 10 m/s²):
