The velocity selector shown below allows a 2 µC charged particle to pass through without being deflected as long as its velocity is v = 5,500 m/sec. Which of the following statements are True/False? positive plate X X X X X X X X X X X X X X X negative plate If v = 4,500 m/sec, a negative charge deflects left. True If v = 6,500 m/sec, a positive charge deflects right. True If B is increased, all negative charges with v = 5,500 m/sec deflect left. False Any charged particle traveling at 5,500 m/sec passes through undeflected. True If E is increased, all positive charges with v = 5,500 m/sec deflect right. True Note: you MUST complete all sentences before submitting.

A small positive test charge of 0.02C is situated 1.5m away from a positive charge of 1C and 4.2m away from a second positive charge of 14C. What is the total potential energy of the test charge. The coulomb constant K = 9E9. Give your answer in GigaJoules (GJ)

A 2.0 µC charge is placed in air. How much work needs to be done to carry a 0.05 µC of charge from a distance of 50 cm to 10 cm around the 2.0 µC charge? (Work W = qtest ∙∆V) Group of answer choices 7.2 kJ 7.2 mJ 0.072 J 7.2 J

This time your object has a mass of 20.4 kg. Now imagine taking all the protons out of the object and stuffing them into a box. Also take all the electrons out of the object and stuff them in a second box. How much charge is contained in the box with all the protons?   Question 2 options:   3.90E+09 C   4.89E+08 C   9.77E+08 C   1.95E+09 C

A student is trying to build a home-made capacitor. He uses two 1.0 cm x 1.0 cm aluminum foil as the two parallel conducting plates, spaced 0.40 cm apart. He then connects the two foils with a 3.0 V battery. How many electrons are stored in the negative plate?

Two parallel, oppositely-charged, large metal plates are 2.3 cm apart.  There is a 19,000 V difference between the plates.  A drop of oil with a net charge of 9.1 nC is between the two plates.  What is the magnitude of the electric force on the drop?

Determine the initial acceleration of the dust particle.

An eletrostatic paint sprayer consists of a charged metal sphere. Charged paint droplets (the sign the same as the metal sphere) are shot towards the metal sphere using a paint gun. The paint droplets repel and move towards a grounded object that needs to be painted. In the figure below, an electrostatic paint sprayer has a 0.25 m diameter metal sphere at a potential Vsphere of 23 kV that repels paint droplets onto a grounded wall.  a) What charge is on the sphere? b)    What charge must a 0.14 mg drop of paint have to arrive at the object with a speed of 12 ms?
