$4.667$ $4.667$ meters

Explanation:

In a balanced lever, product of mass of one weight and its distance from fulcrum is equal to the mass of other weight and its distance from the fulcrum. As the product is $14$ $14$ in first weight, the distance of second weight from fulcrum would be $\frac{14}{3}$ $14/3$ i.e. $4.667$ $4.667$ meters.
