The left end of a 1-kg, 1.0 m long uniform thin rod is attached to a pivot, about which it can rotate freely. A force F is applied at the right end of the rod at 30 degree angle to hold the rod stationary in a horizontal position. What is the magnitude of the force F?

I think the answer is 10N but I have no clue how to solve it.
