An airplane is flying through a thundercloud at a height of 2200 m. (This is very danger- ous because of updrafts, turbulence, and the possibility of electric discharge.) If there are charge concentrations of 23 C at height 4700 m within the cloud and -28 C at height 779 m, what is the strength of the electric field E at the aircraft? The Coulomb constant is 8.99 × 10° N-m²/C?. Answer in units of V/m.

An airplane is flying through a thundercloud at a height of 1900 m. (Flying at this height is very dangerous because of updrafts, turbulence, and the possibility of electric discharge.) If there are charge concentrations of +40.0 C at a height of 3350 m within the cloud and -40.0 C at a height of 1000 m, what is the electric field at the aircraft? (Give the magnitude and direction.) Magnitude  N/C

A bowling ball of regulation diameter (22.0 cm) hasn’t yet been drilled for finger holes and is charged throughout its volume. If the charge is spread uniformly and has a total value of positive 15.0.0 C, how strong is the electric field (b) 5.5 cm, (c) 22.0 cm, from the ball’s center?
