Q2. Read the following paragraph and answer the questions.
A charged particle moving in a magnetic field experiences a force that is proportional to the strength of the magnetic field, the component of the velocity that is perpendicular to the magnetic field and the charge of the particle. This force is given by F = q(⃗ v ×B ) where q is the electric charge of the particle, v is the instantaneous velocity of the particle, and B is the magnetic field (in tesla). The direction of force is determined by the rules of cross product of two vectors. Force is perpendicular to both velocity and magnetic field. Its direction is same as
(⃗ v ×B ) if q is positive and opposite of (⃗ v ×B ) if q is negative the force is always perpendicular to both the velocity of the particle and the magnetic field that created it. Because the magnetic force is always perpendicular to the motion, the magnetic field can do no work on an isolated charge. It can only do work indirectly, via the electric field generated by a changing magnetic field.

(i) When a magnetic field is applied on a stationary electron, it
(a) remains stationary
(b) spins about its axis
(c) moves in the direction of the magnetic field

(a) the proton will be accelerated along the axis
(b) the proton path will be circular about the axis
(c) the proton moves along helical path
(d) the proton will continue to move with velocity v along the axis.

(iii) A charged particle experiences magnetic force in the presence of magnetic field. Which of the following statement is correct?
(a) The particle is stationary and magnetic field is perpendicular.
(b) The particle is moving and magnetic field is perpendicular to the velocity
(c) The particle is stationary and magnetic field is parallel
(d) The particle is moving and magnetic field is parallel to velocity
(iv) A charge q moves with a velocity 2 ms1

(iv) A charge q moves with a velocity 2 ms1 along x-axis in a uniform magnetic field ⃗ B= (iˆ + 2jˆ + 3kˆ )T then charge will experience a force
