The maximum kinetic energy of the positive ion in the cyclotron is (a) qBR 2 /2m (b) q 2 B 2 R 2 /2m (c) q 2 B 2 R 2 /m (d) qBR/m Answer 3. Physics Deleted Syllabus Class 12 CBSE 2021-22. D'Alembert's Principle. Cyclotron Frequency Under the action of the given magnetic field (B fixed), the given positive ion (e/m fixed) will cover the semi-circular path in a fixed time only, if t in equation is equal to $\frac {T} {2}$Where T is the time period of the electric field. //www.en.wikipedia.org NCERT Physics Textbook Class 12 Lab Manual Physics.

The working principle of a cyclotron involves the use of an electric field to accelerate charge particles across the gap between two D shaped magnetic field regions. Where, n-number of charges per unit volume, A-area of cross section, l-length of the conductor. Cyclotron was designed by Lawrence and Livingstone in 1931. The magnetic force
