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.
