Conditions for equilibrium

Two identical charged spheres of mass $0.20\,\text{kg}$ hang from a common point on light strings of length $0.40\,\text{m}$. Each string makes an angle of $4.0^\circ$ with the vertical due to electrostatic repulsion. The horizontal electrostatic force on each sphere is $0.14\,\text{N}$. What is the weight of each sphere?
