AN airplane is flying through a cloud. The airplane is at 2100M and the top height of the cloud is 4100M @ 23 C. The bottem of the cloud is 500m @-47 C. What is the strength of the electric field E at the aircraft. Now I broke it up into to parts, for the top of the cloud and the bottem. Top of the cloud: Using coulumbs law: 8.98755 x 10^9* 23/ 4100-2100) = 1.03357e8 Bottem of the cloud: 8.98775 x 10^9 * 47/ 2100-500 = 2.64009e9 I added both of those up and i submited my answer and it said it was wrong. Can anyone aid me?
