An airplane is flying through a thundercloud at a height of 2000 m. If there is a charge concentration of +40C at height 3000 m within the cloud and -40 C at height 1000 m, what is the magnitude of the electric field E at the aircraft?

(k_e = 8.99 × 10⁹ N·m²/C²).

Part A) A cylindrical shell of radius 8.9 cm and length
299 cm has its charge density uniformly dis-
tributed on its surface. The electric field
intensity at a point 21.4 cm radially outward
from its axis (measured from the midpoint of
the shell ) is 47900 N/C.
Given: ke = 8.99 Ã 109 N Â· m2/C2 .
What is the net charge on the shell?
Answer in units of C.
