Question

Two charges $q_1 = -3.20$ nC and $q_2 = +8.16$ nC are at a distance of $1.06$ $\mu$m from each other. $q_1$ is fixed at its location while $q_2$ is released from rest. (a) What is the kinetic energy of the charge $q_2$ when it is $0.340$ $\mu$m from $q_1$? What is the electric potential at the initial and final locations of the moving charge due to the fixed charge? What is the change in electric potential energy of the moving charge? J (b) The charge $q_2$ has a mass $m_2 = 7.85$ $\mu$g. What is its speed when it is $0.340$ $\mu$m from $q_1$? How is kinetic energy related to the speed of the particle? m/s

Step 1

06 \ \mu m = 1.06 \times 10^{-6}$ m. The final distance between the charges is $r_f = 0.340 \ \mu m = 0.340 \times 10^{-6}$ m. The initial potential energy is $U_i = \frac{k q_1 q_2}{r_i}$, where $k = 8.99 \times 10^9 \ N m^2/C^2$. $U_i = \frac{(8.99 \times 10^9 \ Show more…
