Question

In a vacuum, two particles have charges of q1 and q2, where q1 = +3 μC. They are separated by a distance of 35 cm, and particle 1 experiences an attractive force of 3.34 N. What is q2 in μC (magnitude and sign)? (k = 9.00 x 109 N.m2/C2)?

Answer 1

- We know that the force between two charge particles F=K9, 2 Here F=3.34N = 2 = 22 8=35cm=0.35m 9 = 3x10cc к , K29x105 Nm/al 9 = 3.34 x (0.35) (9x109x3x106) / 2 = 61.515x10 S 9 2 15.15x156 magnitude 9 = 15.246 nee unlike charge attract so it is negative. Means it has negative sign means 9= -15.are
