009 An airplane is flying through a thundercloud at a height of 2100 m. (This is very danger- ous because of updrafts, turbulence, and the possibility of electric discharge.) If there are charge concentrations of 25 C at height 3200 m within the cloud and –45 C at height 753 m, what is the strength of the electric field E at the aircraft? The Coulomb constant is 8.99 × 10º N-m²/C². Answer in units of V/m.
