An electron travels in a vacuum tube that is 2 meters in length .002 seconds what is the average speed of the electron during this time

Answer : The average speed of the electron during this time is 1000 m/s

Explanation :

Average speed : It is defined as the ratio total distance to total time.

Formula used :

As per question,

Total distance traveled by electron = 2 m

Total time taken by electron = 0.002 s

Now put all the given values in the above formula, we get:

Therefore, the average speed of the electron during this time is 1000 m/s

it should be p1 v1 = p2 v2

im pretty sure its b
