← A small circular loop of radius 1 cm lies at the centre of a large circular loop of radius 10 cm, in the same plane, as shown in the figure. Take µ₀ = 4π × 10⁻⁷ T m/A. The mutual inductance of the pair is closest toA proton and an alpha particle have the same kinetic energy. Both enter the same uniform magnetic field at right angles to it and move in circles. The ratio of the radius of the alpha particle's circle to that of the proton's is →
