When a charged particle enters a uniform magnetic field its kinetic energy

When a positively charged particle enters a uniform magnetic field with uniform velocity, its trajectory can be a) a straight line b) a circle c) a helix

Assertion If a charged particle enters from outside in uniform magnetic field, then it will keep on rotating in a circular path. Reson Magnetic force is always perpendicular to velocity vector.

Assertion When a charged particle moves perpendicular to a uniform magnetic field then its momentum remains constant. Reason Magnetic force acts perpendicular to the velocity of the 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.

If a charged particle enters perpendicular in the uniform magnetic field then

A charged particle enters a uniform magnetic field perpendicular to it. The magnetic field

A charged particle enters in a uniform magnetic field perpendicular to it. Now match the following two columns.

A charged particle enters into a uniform magnetic field with velocity v_(0) perpendicular to it , the length of magnetic field is x=sqrt(3)/(2)R , where R is the radius of the circular path of the particle in the field .The magnitude of charge in velocity of the particle when it comes out of the field is
