Question

A particle with a charge of -3.5 µC and a mass of 4.4 x 10-6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 45 m/s. The only force acting on the particle is the electric force. What is the potential difference VB - VA between A and B? If VB is greater than VA, then give the answer as a positive number. If VB is less than VA, then give the answer as a negative number.

Step 1

$$\Delta KE = KE_f - KE_i = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2$$ Since the particle starts from rest, $v_i = 0$. $$\Delta KE = \frac{1}{2}mv_f^2 = \frac{1}{2}(4.4 \times 10^{-6} kg)(45 m/s)^2 = \frac{1}{2}(4.4 \times 10^{-6})(2025) = 4.455 \times 10^{-3} J$$ Show more…
