4) An astronaut standing at radius R1 on the inner ring of this space station moves a distance X1 along a circular arc as the station rotates.
A) Over what distance X2 does another astronaut at radius R2 on the outer ring move in the same time?
B) Over what angle, in degrees, did the space station rotate in this period, expressed in terms of R1 and X?

The space station is rotating to create artificial gravity. The speed of the inner ring is one half that of the outer ring. As an astronaut walks from the inner to the outer ring, what happens to her apparent weight? choice on of them? Her apparent weight becomes four times as great. Her apparent weight does not change. Her apparent weight becomes one-fourth as great. Her apparent weight becomes half as great.

Determine the electric eld a distance z above the center of a ring with charge uniformly distributed between an inner radius R1 and an outer radius R2 (alternatively, you can describe this as a disk of radius R2 with a circular hole of radius R1). Do this two ways: by directly performing an integral over the surface of the ring and by superposition.

A long, hollow cylinder with inner radius R1 and outer radius R2 carries current along its length. The current is uniformly distributed over the cross-sectional area of the cylinder and has current density J. 1. Find the magnetic-field magnitude B as a function of the distance r from the conductor axis for points inside the hollow interior (r<R1). Express your answer in terms of the variables R1, R2, J, and r. 2. Find the magnetic-field magnitude B as a function...

FR2 R1 х A flat ring of inner radius R, and outer radius Ry has a uniform surface charge density of o. Find an expression for the electric field for points along the x-axis in two ways: (a) Calculate the potential first by treating the ring as a continuous charge distribution. Then find the electric field from the potential. (b) Calculate the electric field directly by treating the ring as a continuous charge distribution.
