A cylindrical shell of radius 7.00 cm and length 2.57 m has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 16.0 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C. Required:
a. Use approximate relationships to find thenet charge on the shell.
b. Use approximate relationships to find theelectric field at a point 4.00 cm from the axis, measured radiallyoutward from the midpoint of the shell.

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

neither accurate nor precise.
