Suppose N electrons can be placed in either of two configurations. In configuration 1, they are all placed on the circumference of a narrow ring of radius R and are uniformly distributed so that the distance between adjacent electrons is the same everywhere In configuration 2, N − 1 electrons are uniformly distributed on the ring and one electron is placed in the center of the ring, (a) What is the smallest value of N for which the second configuration is less energetic than the first? (b) For that value of N , consider any one circumference electron—call it e 0 . How many other circumference electrons are closer to e 0 than the central electron is?

Two-point charges of 5.00 µC and -3.00 µC are placed 0.250 m apart.a) What is the electric force on each charge? Include strength and direction and a sketch.b) What would be the magnitude of the force if both charges are positive? How about the direction?
c) What will happen to the electric force on each piece of charge if they are moved twice as far apart? (Give a numerical answer as well as an explanation.)

The figure shows two snapshots of a single wave on a string. The wave is
traveling to the right in the +x direction. The solid line is a snapshot of the wave
at time t=0 s, while the dashed line is a snapshot of the wave at t=0.48s.
