Answer:
the speed of electron is 4.42 x 10⁶ m/s
the speed of proton is 2406.7 m/s
Explanation:
Given;
electric field strength, E = 478 N/C
charge of the particles, Q = 1.6 x 10⁻¹⁹ C
mass of proton, Mp = 1.673 x 10⁻²⁷ kg
mass of electron Me = 9.11 x 10⁻³¹ kg
time of motion, t = 54.2 ns = 54.2 x 10⁻⁹ s
The magnitude of charge experienced by the particles is calculated as;
F = EQ
F = 478 x 1.6 x 10⁻¹⁹
F = 7.648 x 10⁻¹⁷ N
The speed of the particles is calculated as;
