A solid, spherical plastic ball (of radius a) is given a net charge of +4Q Coulombs. The charge is distributed uniformly throughout the volume of the ball. a.) Determine the total charge enclosed by a Gaussian surface of radius r = a/2 b.) Use Gauss's Law to determine an expression for the electric field at r = a/2. Use the symbol kE in your answer. Do not forget to include a unit vector, since the electric field is a vector.

1. (10 points) A cylindrical can has a height of 15 mm and an initial radius of 16 mm. The volume of the cylindrical can is decreasing at a rate of 541 cubic mm per minute, with the height being held constant. What is the rate of change, in mm per minute, of the radius when the radius is 3 mm? Remember to include a negative sign if the radius is decreasing. 2. (10 points) Use a...
