The number of revolutions made by the electron are f = 1.64 x 10^15 m/s
Explanation:
As we know that
f = v2 / 2 π r2
For radius "r2" = (2)^2 0.529 x 10^-8 cm / s = 4 x 0.529 x 10^-10 m /s
r2 = 2.12 x 10^-10 m /s
f = 2.18 x 10^6 m/s / 2.12 x 10^-10 m /s x 2 x 3.14
f = 2.18 x 10^6 + 10 / 2.12 x 2 3.14
f = 2.18 x 10^16 / 13.31
f = 0.164 x 10^16 m / s
f = 1.64 x 10^15 m/s
