Part A: A foam block that contains a charge of 0.0054 coulombs (C) experiences an electrostatic force of 8 newtons (N) from a foam ball 30 centimeters (cm) away. How much charge is on the ball? Part B: Create a question about a foam ball experiencing 224 newtons of force that uses Newton's Third Law of Motion to answer it. Then answer it. Part C: A typical bolt of lightning carries billions of joules (1 GJ = 109 J) of energy, but discharges it over a very short period of time. If a particular lightning bolt discharges 8 GJ of energy in 30 microseconds (1 µs = 10-6 s), then how many watts (W) of power did it deliver? Express your answer in scientific notation.

Two charges lie in a line along the x axis. Charge 1 is q1 = 1.1 C and charge 2 is q2 = 2.15 C. They are each a distance of d = 0.093 m from the origin. What is the distance on the x-axis from the origin at which the electric field will be zero. Give your answer in meters.

Two point charges each with 0.15 CC of charge are 5.0×10−2 mm apart. Knowing that k is 9×10^9N⋅m^2/C  (the proportionality constant for Coulomb's law), find the force between the charges. Express your answer to two significant figures and include the appropriate units.

A charge of +3.17mC is placed in a region where an electric field is present.  If the magnitude of the electric field is 284.9 N/C, what is the magnitude of the electric force on this charge in units of Newtons? Note:  It is understood that the unit of your answer is in Newtons, however do not explicitly include units in your answer.  Enter only a number.

A particle with a mass of 3.65×10−24 kg and a charge of 6.40×10−19 C starts at rest and is accelerated for a distance of 0.0980 m through a uniform electric field having strength E = 7.25×104 N/C. What is the resulting speed of the particle?

In the picture below, the rod is positively charged. Electrically speaking, water is a "polar molecule"; each water molecule can be imagined as a negative charge (the oxygen end) and a positive charge (the hydrogen end), each of approximate magnitude 2e, separated by an approximate distance of 2 x10-1" m. a) Explain how a charged rod can exert an electric force on water molecules that have zero net charge. Include a picture of a typical water molecule in the stream of water adjacent to the rod, showing its orientation relative to the rod. b) If the charge of the rod is +32 nC and that charge is located approximately 2.0 cm from a water molecule in the stream, what is the maximum possible net electric force that the rod could exert on the molecule?
