In the Figure,a Force F Is Being Applied to the Block

In the figure,a force F is being applied to the block with a magnitude such that it moves up along the frictionless inclined place with a constant velocity of 5 m/s.The angle in the figure is 30 ^$\circ$ ,and the mass of the block is 50 kg.How much work (in Joules) is done by the force F in moving the block 10 meters along the surface of the inclined plane (within 5% accuracy) ?

A) 500 J
B) 2500 J
C) 4200 J
D) 5000 J
E) zero
