#2 (2 points) A small mobile particle is placed at a position in space that experiences an
electric potential of 24 V. This electric potential gives the particle a potential energy of -2.5
J. What is the charge of this particle (include your sign)?
Final Answer:
#3 (7 points) A +1.82 μC charge is moving towards a stationary, field generating +4.80 mC
charge. What is the change in potential energy as the +1.82 μC charge moves from 50.0 cm
away to only 9.80 mm away from the stationary charge?
Final Answer:
2

#4 (9 points) A mobile –5.40 mC charge (m = 230.0 g) is placed 45.0 cm from a –15.1 mC
stationary charge that is generating an electric field. If the -5.40 mC charge starts from rest
and starts moving away from the stationary charge how fast will it be traveling when it
reaches 240.0 cm away?

#5 (5 points) If a freely moving charged particle (m = 4.8 x 10-14 kg, q = +1.6 x 10-19 C) starts
at rest and travels from the positive plate of a 4.9 x 10-8 F capacitor to the negative plate, how
fast will it be moving? Assume the capacitor has 1.40 mC of stored charge.
Final Answer:
