Dear Student,
Please find below the solution to your problem.
Fe from previous problem No. 18 = 8.2 × 10^–8 N Ve = ?
Now, M base e = 9.12 × 10^–31 kg
r = 0.53 × 10^–10 m
Now, Fe = M base ev^2/r
⇒ v^2 = Fe * r/m base e = 8.2 * 10^-8 * 0.53 * 10^-10/9.1 * 10^-31
= 0.4775 * 10^13
= 4.775 * 10^12 m^2/s^2
⇒ v = 2.18 * 10^6 m/s
Thanks and Regards
