Two identical small metal spheres with q1 > 0 and |q1| > |q2| attract each other with a force of magnitude 77.9 mN when separated by a distance of 1.79 m . Now the spheres repel each other with a force of magnitude 7.79 mN. What is the final charge on the sphere on the right?

Me with this and you will be marked brainliest
