Aconducting sphere of radius r carries positive charge q. calculate the amount of work that would be required to move a small positive test charge q0 slowly from r=5r to r=3r. assume that the presence of q0 has no effect on how the charge q is distributed over the sphere.
express your answer in terms of the electric constant ϵ0 and some or all of the variables q, q0, and r.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
