Question
Particle that carries a net charge of -95.8 mu C is held in a region of constant, uniform electric field. The electric field vector is oriented 55.2 degree clockwise from the vertical axis, as shown. If the magnitude of the electric field is 5.32 N/C, how much work is done by the electric field as the particle is made to move a distance of d = 0.756 m straight up? J What is the potential difference between the particle's initial and final positions (V_f - V_i)? Incorrect. Negatively charged particles tend to move towards higher potential. Which direction would the particle move if it were let go?Explanation / Answer
F = qEy = qEcos55.2 = 2.9e-4 N
Work done = F.d = 2.9-4 * 0.756 = 2.2e-4 J
W = qV
V = 2.2e-4 / 95.8e-6 = 2.3 V
