Problem 1: a positively charged particle q1 = +35 nc is held fixed at the origin. a second charge q2 of mass m = 8.5 micrograms is floating a distance d = 25 cm above charge q1. the net force on q2 is equal to zero. you may assume this system is close to the surface of the earth. a) what is the sign of charge on q2? b) calculate the magnitude of q2 in units of nanocoulombs.

This problem has been solved! See the answer. Two charged particles, Q 1 = + 5.10 nC and Q 2 = -3.40 nC, are separated by 40.0 cm. (a) What is the ... has not been graded yet. (b) What is the electric potential at a point midway between the charged particles? (Note: Assume a reference level of potential V = 0 at r = infinity .)

Explanation:

fgravity=10x10=100n case 1
