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
