    The cyclotron is a device which is used to accelerate charged particles such as protons, deutrons, alpha particles, etc. to very high energy. The principle on which a cyclotron works is based on the fact that an electric field can accelerate a charged particle and a magnetic field can throw it into a circular orbit. A particle of charge +q experiences a force qE in an electric field E and this force is independent of velocity of the particle. The particle is accelerated in the direction of the magnetic field. On the other hand, a magnetic field at right angles to the direction of motion of the particle throws the particle in a circular orbit in which the particle revolves with a frequency that does not depend on its speed. A modest potential difference is used as a sources of electric field. If a charged particle is made to pass through this potential difference a number of times, it will acquire an enormous by large velocity and hence kinetic energy. Cyclotron is not suitable for accelerating

Which of the following cannot be accelerated in a cyclotron?

    Assertion(A): Total work done by non-unifrom electric field on a charged particle starting from rest to any time is non-negative (Assume no other forces act on the charged particle) Reason(R ):the angle between electrostatic force and velocity of the charged particle released from rest in non-uniform electric field is always acute. (Assume no other forces act on the charged particle)

    STATEMENT-1 : If a charge particle enters into a uniform electric field, then its path must be straight line. and STATEMENT -2 : Electrostatic force on a positive charge particle is always in the direction of electric field.
