Cyclotron MCQ - Practice Questions with Answers

Cyclotron is a device which is used to

When a proton is accelerated through 1 V, then its kinetic energy will be:

An alternating electric field, of frequency v, is applied across the dees (radius = R) of a cyclotron that is being used to accelerate protons (mass = 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 proton, deuteron and particle having the same kinetic energy are moving in circular trajectories in a constant magnetic field. If r_p, r_d and r denote their radii respectively, the correct order of radii:

Alpha particles $\left(m=6.7 \times 10^{-27} \mathrm{~kg}\right)$ and $q=+2 e$ are accelerated from rest through a potential difference of 6.7 KV. Then, they enter a magnetic field $B=0.2 T$ perpendicular to the direction of their motion. The radius of the path described

An electron experiences no deflection if subjected to an electric field of $3.2 \times 10^5 \mathrm{v} / \mathrm{m}$ and a magnetic induction of $2.0 \times 10^{-3} \tau$. Both the fields are applied perpendicular to the path of the electron and also to each other. If the electric field is removed then the electron will revolve in an orbit of radius

A particle of charge $\mathbf{q}$ and mass $\mathbf{m}$ is projected with a velocity $v_0$ towards a circular region having uniform magnetic field $\mathbf{B}$ perpendicular and into the plane of paper form point $\mathbf{P}$ as. $\mathbf{R}$ is the radius and $\mathbf{O}$ is the centre, The value of $v_0$ so that particle passes through $O$ is -

An alternating electric field, of frequency v, is applied across the dees (radius =R) of a cyclotron that is being used to accelerate protons (mass = 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:
