Hat Magnetic

An electron with speed 30m/s and an angle of 60 to the x axis has a path that passes through the origin?

An electron with speed 30m/s and an angle of 60 to the x axis has a path that passes through the origin?

1.)Using an x,y graph what is the magnetic (B) field at point 2,2?

2.) A wire carrying a 5Amp current in the k-hat direction passes through point (2,2) what is the force the electrons magnetic field exerts on the wire?

I am more looking for the method, formulas and steps, to solving this rather as well as the exact answer. Thanks much
The length of the wire is infinite.

1) The magnetic field is coming out of the page if the electrons travels in the directions of Quadrant I where both x and y axis have positive numbers.

The distance from (2,2) to the path of the electron is 0.366 m.
Current induced is:
I = Q/t = 1.60×10^-19 / (4/30) = 1.20×10^-18 A.
Magnetic field is:
B = (μo I)/(2πr) = 4πx10^-7 x 1.20×10^-18 / (2π x 0.366) = 6.56 T, with the direction of the positive z axis.

2) (not enough info). Length of the wire is needed into to determine speed the charge within the wire, and then be able to use F = v x B to determine the direction & and magnitude of the force. If the situation were reversed, where the force exerted on the electron is sought, the conditions for the formula will be satisfied.
