Question

Each of the electrons in a particle beam has a kinetic exergy of 1.00 times 10^-17 J. What is the magnitude of the uniform electric field (pointing in the direction of the electrons movement) that will stop these electrons in a distance of 7.0 cm? How long will it take to stop the electrons? Your response differs significantly from the correct answer Rework your solution from the beginning and check each step carefully, ns After the electrons stop, the electric field will continue to act on them, causing the electrons to accelerate in a direction

Explanation / Answer

b) S = ut + 0.5at^2

0.07 = 0 + 0.5*(qE/m) * t^2

0.07 = 0.5* (1.6*10^-19 * 892.9 / 9.11*10^-31) * t^2

t = 2.98*10^-8 s
