The practical limit to an electric field in air is about 3.00 x 10 6 N/C. Above

Question:

The practical limit to an electric field in air is about 3.00 x 10⁶ N/C. Above this strength, sparking takes place because air begins to ionize and charges flow, reducing the field.

(a) Calculate the distance a free proton must travel in this field to reach 3.00% of the speed of light, starting from rest.

(b) Is this practical in air, or must it occur in a vacuum?
