Two infinite long wires, each carrying current I, are lying along x- and y-axis, respectively. A charged particle, having a charge q and mass m, is projected with a velocity u along the straight line OP. The path of the particle is (neglect gravity)

A

Straight line

B

circle

C

helix

D

cycloid

Text Solution

Verified by Experts

The correct Answer is:
A
(a) B at all the point lying on OP is zero so u will not be affected
by the magnetic force. Hence, it moves on a straight line.
