Physics Circular Motion

Question

In the Bohr model of the hydrogen atom, the speed of the electron is approximately 2.32 × 106 m/s.

(a) Find the central force acting on the electron as it revolves in a circular orbit of radius 5.28 × 10−11 m.

Answer in units of N.

(b) Find the centripetal acceleration of the electron. Answer in units of m/s 2 .

Answer 1

F = mV²/r where r = radius of orbit, m = the mass of an electron, V = speed of electron

a = V²/r

Substitute the values in the equations and solve using a calculator
