1. Two charges are arranged on the x axis. q1 = +8.00 μC, and
q2 = +5.00 μC. a = 25.0 cm. q1 is held fixed and q2 is released from rest.
Both q1 and q2 have a mass of 20.0 g.
Calculate x2, the position of q2, when it reaches a speed of 8.00 m/s.
a is the distance between q1 and q2. q1 is at the origin and q2 is along the x-axis at a distance "a"
2. Ek= 1/2mv^2
V = kq/r
3.
first i converted m to kg = 20 x 10^-3
Ek = 1/2mv^2
V = kq1/r + kq2/r
1/2mv^2 = kq1/r + kq2/r
1/2(20x10^-3)(8)^2 = k(8x10^-6)/x + k(5x10^-6)/(x-0.25)
solving for x gives me wrong answer
