Questiondetails:
several planets (jupiter, saturn, uranus) possess nearly
circular surrounding rings, perhaps composedof material that failed
to form a satellite. in addition, many galaxies contain ring-like
structures. consider ahomogeneous ring of mass m and radius
r.
a.)what gravitational attractiondoes it exert on a
particle of mass m located a distance x from thecenter of the ring
along its axis?
b.) supposes the particle falls fromrest as a result of
the attraction of the ring of matter. find an expression for the
speed with which it passes through thecenter of the
ring.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
