Final answer:
The central force acting on the electron in the Bohr model of the hydrogen atom is approximately 2.73 x 10^-8 N.
Step-by-step explanation:
The central force acting on the electron in the Bohr model of the hydrogen atom can be determined using the equation:
Centripetal force = Mass x (Speed)^2 / Radius
Given that the mass of the electron is 9.11 x 10^-31 kg, the speed of the electron is 2.15 x 10^6 m/s, and the radius of the orbit is 5.45 x 10^-11 m, we can substitute these values into the equation to calculate the central force:
Centripetal force = (9.11 x 10^-31 kg) x (2.15 x 10^6 m/s)^2 / (5.45 x 10^-11 m)
Calculating the above expression, we find that the central force acting on the electron is approximately 2.73 x 10^-8 N.
