Question 1 Report
An electron of mass 9.1 x 10\(^{-31}\) kg moves with a speed of 2.0 x 10\(^6\) ms\(^{-1}\) round the nucleus of an atom in a Circular path of radius
6.1 x 10\(^{11}\) m. Calculate the centripetal force acting on the electron.
Answer Details
The centripetal force acting on an electron moving in a circular path around the nucleus of an atom is given by the equation:
F = (mv\(^2\))/r
Where F is the centripetal force, m is the mass of the electron, v is the velocity of the electron, and r is the radius of the circular path.
Substituting the given values into the equation, we have:
F = (9.1 x 10\(^{-31}\) kg) x (2.0 x 10\(^6\) ms\(^{-1}\))\(^2\) / (6.1 x 10\(^{11}\) m)
F = 6.0 x 10\(^{-8}\) N
Therefore, the correct answer is: 6.0 x 10\(^{-8}\) N.
