USD student here, and I need some physics help! I suck at physics, and I've been trying to figure these out for like 6 days and I don't even know where to begin!
Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.0898 N when their center-to-center separation is 39.6 cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.0337 N. Of the initial charges on the spheres, with a positive net charge, what was (a) the negative charge in coulombs on one of them and (b) the positive charge in coulombs on the other?
A particle of charge Q is fixed at the origin of an xy coordinate system. At t = 0 a particle (m = 0.931 g, q = 4.49 µC is located on the x axis at x = 16.0 cm, moving with a speed of 36.1 m/s in the positive y direction. For what value of Q (in μC) will the moving particle execute circular motion? (Neglect the gravitational force on the particle.)
