- The practical limit to the strength of an electric field in the air is about 3.00 × 106 N/C . Above this strength, sparking takes place because air begins to ionize and charges flow, reducing the field strength. a) Calculate the distance, in meters, a free proton must travel in this field to reach 2.8 % of the speed of light, starting from rest.Please explain Keatly 'aind cleardy with Equationo oShowrng the corest process Yand answees I have tilud tuwo way La(6). and only gethe same answeifor 10 Quest ioi (6).
