An airplane is flying through a thundercloud at a height of 2 500 m.(This is a very dangerous thing to do because of updrafts,turbulence,and the possibility of electric discharge. ) If there is a charge concentration of +42 C at height 4 000 m within the cloud and −42 C at height 500 m,what is the magnitude of the electric field E at the aircraft? (ke = 8.99 × 109 N·m2/C2)
A) 9.4E+4 N/C
B) 1.7E+5 N/C
C) 6.2E+4 N/C
D) 2.6E+5 N/C
E) 1.9E+5 N/C
