Asolid cylinder (centered along the z-axis, bottom face at z =0, top face at z=l, radius r) carries a volume charge distribution p(z) = kz, where k is a positive constant. a. calculate the electric field at an arbitrary point on the z-axis (x= 0, y = 0, z). b. write an integral expression for the electric field at an arbitrary point (x, y, z). c. sketch the electric field.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
