It is not possible for a charged particle to move in a circular path around a long straight uncharged

Question

(A) Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.

(B) Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.

(C) Statement-1 is true, statement-2 is false.

(D) Statement-1 is false, statement-2 is true. 

Statement-1 : It is not possible for a charged particle to move in a circular path around a long straight uncharged conductor carrying current under the influence of its magnetic field alone.

Statement-2: The magnetic force (if nonzero) on a moving charged particle is normal to its velocity.

Answer 1

Magnetic field at any point is in tangential direction. So it is not possible for a particle to move in tangential direction by the action of magnetic force.
