Question

An electron in a cathode-ray-tube (CRT) accelerates uniformly from 9.00 ✕ 104 m/s to 6.00 ✕ 106 m/s over 1.00 cm.

An electron in a cathode-ray-tube (CRT) accelerates uniformly from 9.00 x 104 m/s to 6.00 x 10° m/s over 1.00 cm.
(a) In what time interval does the electron travel this 1.00 cm?
0.00000000164
Your response differs from the correct answer by more than 10%. Double check your calculations. s
(b) What is its acceleration?
36000000000000
Your response differs from the correct answer by more than 100%. m/s2

Expert Solution
Step 1

Initial speed of electron (u) = 9×104 msFinal speed of electron (v) = 6×106 msdistance moved (d)  =1 cm = 0.01 m mass of electron = 9.11×10-31 kg charge of electron = - 1.6×10-19C
