    The correct answer is A. 250N

    Work is a product of force and distance.

    That is, work done=force*distance

    Therefore substituting for the values in the question:

    500J=force*2m

    force = 500Nm/2m=250N

    another unit for work done is Nm as force as the SI unit of force is newtons and distance in meters
