Answer:
it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
Explanation:
Magnetic field is along z axis while velocity is in x-z plane
so we will have
so here we can say
so we will have
so here the net force on the charge is perpendicular to its x directional velocity along - Y direction
So due to this component of motion it will move along a circle while other component of the motion will remain uniform always
So here it is combination of two parts
1) Uniform circular motion
2) Uniform motion
So we can say that it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
The magnetic field generated by a wire that carries a current of intensity I is :
where
is the magnetic permittivity
I is the current
r is the radial distance from the wire at which the field is calculated.
In our problem, I=65 A and r=12 cm=0.12 m, so the magnetic field is:
And we can see that the intensity of this magnetic field at r=12 cm is approximately twice the intensity of the Earth's magnetic field (
