Three magnets are placed on a plastic stick as shown in the image. Explain how the magnets need to be rearranged so that they stick together and why rearranging them this way allows them to stick together.

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
