Conclusion of Rutherford's scattering experiment: Most of the space inside the atom is empty because most of the -particles passed through the gold foil without getting deflected.Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space. This deflection idea has been tested and verified. Because the magnetic force F supplies the centripetal force \(F_C\), we have, Here, r is the radius of curvature of the path of a charged particle with mass m and charge q, moving at a speed v that is perpendicular to a magnetic field of strength B.
