Question

HELP PLEASE!

1.) Two point charges are fixed on the y axis: a negative point charge q1 = -26 µC at y1 = +0.20 m and a positive point charge q2 at y2 = +0.30 m. A third point charge q = +8.6 µC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 22 N and points in the +y direction. Determine the magnitude of q2.

2.) A charge of -3.25 µC is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass, which has a radius of 0.096 m. The charges on the circle are -4.25 µC at the position due north and +4.95 µC at the position due east. What are the magnitude and direction of the net electrostatic force acting on the charge at the center? Specify the direction relative to due east. magnitude _N, _direction

3.) In a vacuum, two particles have charges of q1 and q2, where q1 = +3.8 µC. They are separated by a distance of 0.20 m, and particle 1 experiences an attractive force of 3.5 N. What is q2 (magnitude and sign)? magnitude_ C
