An alternating electric field,of frequency $f$,is applied across the dees (radius $\approx R$) of a cyclotron that is being used to accelerate protons (mass $\approx m$). The operating magnetic field $(B)$ used in the cyclotron and the kinetic energy $(K)$ of the proton beam,produced by it,are given by:

  • A
    $B = \frac{mf}{e}$,$K = 2m\pi^2f^2R^2$
  • B
    $B = \frac{2\pi mf}{e}$,$K = \pi m^2f^2R^2$
  • C
    $B = \frac{2\pi mf}{e}$,$K = 2m\pi^2f^2R^2$
  • D
    $B = \frac{mf}{e}$,$K = \pi m^2f^2R^2$

$A$ cyclotron's oscillator frequency is $10 \text{ MHz}$ and the operating magnetic field is $0.66 \text{ T}$. If the radius of its dees is $60 \text{ cm}$, then the kinetic energy of the proton beam produced by the accelerator is: (in $\text{ MeV}$)

Assertion: Cyclotron does not accelerate electrons.
Reason: Mass of the electrons is very small.
