An electron traverses a vacuum tube with a length of 2 m in 2 X 10- 4 sec. What is the average speed of the
electron during this time?

Average speed = 10,000 m/s

Explanation:

Given the following data;

Distance = 2m

Time = 0.0002secs

To find the average speed;

Average speed = distance/time

Average speed = 2/0.0002

Average speed = 10,000 m/s

Therefore, the average speed of the

electron is 10,000 meters per seconds.

double the distance = divide strength by 4
