Force needed to hold a 1000 N wheelbarrow with handles 1 m from the wheel

[abct]

I'm stuck on this question:

What force must a man exert to hold up a wheelbarrow which weighs , with contents, 1000 N? Consider distances to the wheel horizontally from the handles and center of gravity to be 1 m and 0.4 m respectively.

Take the wheel as the fulcrum and 1000N is the load and using 0.4 m as load arm and 1 m as effort arm.
