Air will break down (lose its insulating quality) and sparking will result if the field strength is increased to about 3 × 106 n/c. what acceleration will an electron experience in such a field? the mass of the electron is 9.109 × 10−31 kg and the fundamental charge is 1.602 × 10−19 c. let the electric field lie along the positive x-axis. answer in units of m/s 2

Acceleration,

Explanation:

Given that,

Electric field strength,

Mass of the electron,

Charge on electron,

Let a is the acceleration experienced by an electron. It can be calculated as :

Hence, this is the required solution.

nec chapter 5 contains

c. information on special occupancy areas

nec chapter 6 covers

a. special equipment

which of the following rules contain the words shall or shall not and must be adhered to?

b. mandatory rules

which of the following rules identify actions that are allowed but not required and typically cover options or alternative methods?

c. optional rules

which of the following serves as the introduction to the nec and provides an overview of the book?

a. nec article 90

organizations that test products for safety are

c. nrtls

the nec is published by the

a national fire protection association

the nec is divided into

b. 9 chapters

the nec provides informative annexes for

c. informational materials and examples

two terms from nec article 100 that trainees should become familiar with are

b. labeled and listed

explanation:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
