A disk of radius has a total charge uniformly distributed, Ask an Expert

Academics

Q1. The best leaper in the animal kingdom is the puma, which can jump to a height of 12.4 ft when leaving the ground at an angle of 43°. With what speed, in SI units, should the animal leave ground to reach that height?

Q2. A disk of radius has a total charge uniformly distributed over its surface. The disk has negligible thickness and lies in the xy plane. What is the electric potential V (z) on z axis as a function of z, for z>0?
