# Tension force of string

An object with mass $$3$$ kg is hung on a $$3$$ m long horizontal stick with mass $$6$$ kg. As shown in the above diagram, the two ends of the stick are tied to two strings of equal length suspending perpendicularly to the ceiling. The object is hanging $$1$$ m from the left end of the stick. Find the tension force $$F$$ on the string at the right end (in N).

Gravitational acceleration $$g$$ is $$10 \text{ m/s}^2.$$
