Correct option is D
Cyclotron: A cyclotron works on the principle that an electric field accelerates a charged particle, and the magnetic field keeps it revolving in circular orbits with a constant frequency.
This device is a type of particle accelerator in which a perpendicular magnetic field is applied to the particle's motion plane, causing it to move in a circular path.
Magnetic Force and Centripetal Force:The relationship between the magnetic force and the centripetal force is given by the equation:Bqv=rmv2Simplifying this equation, we find the velocity of the particle v as:v=mBqThe angular velocity ω and radius r also relate in such a way that:ω×r=mBqFrom this, we derive the expression for angular velocity ω:ω=mBqThe cyclotron frequency VC is given by the formula:VC=2πmqB
