QUESTION:

Problem 59PE

Integrated Concepts The practical limit to an electric field in 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. (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?
