Answer:
Distance travelled, d = 0.21 m
Explanation:
It is given that,
Initial velocity of electron, u = 500,000 m/s
Acceleration of the electron, a = 500,000,000,000 m/s²
Final velocity of the electron, v = 675,000 m/s
We need to find the distance travelled by the electron. Let distance travelled is s. Using third equation of motion as :
s = 0.205 m
or
s = 0.21 m
So, the electron will travel a distance of 0.21 meters. Hence, this is the required solution.
