In a cyclotron,the time taken by an ion to describe a semicircular path in a dee is

In a cyclotron,the angular frequency of a charged particle is independent of

$A$ charged particle moves along a circular path in a uniform magnetic field in a cyclotron. The kinetic energy of the charged particle increases to $4$ times its initial value. What will be the ratio of the new radius to the original radius of the circular path of the charged particle?

In a cyclotron,a charged particle

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

If the maximum value of accelerating potential provided by a radio frequency oscillator is $12 \, kV$,the number of revolutions made by a proton in a cyclotron to achieve one-sixth of the speed of light is ....... .
