Multiple-Concept Example 4 deals with the concepts that are important in this problem. As illustrated in the figure, a negatively charged particle is released from rest at point B and accelerates until it reaches point A. The mass and charge of the particle are 7.88 x 10-4 kg and -6.59 x 10-5 C, respectively. Only the gravitational force and the electrostatic force act on the particle, which moves on a horizontal straight line without rotating. The electric potential at A is 36.0 V greater than that at B; in other words, VA - VB = 36.0 V. What is the translational speed of the particle at point A?
UB = 0 m/sExplanation / Answer
v = (-2qV / m)^(1/2)
= ((-2 * (-6.59*10^-5 C) * 36.0 V) / (7.88*10^-4 kg))^(1/2)
= 2.45 m/s
