Athin wire oriented along the x-axis carries a current i in the +x direction. at a certain instant, a point charge +q is coincident with the point (x, y, z)= (0, a, 0) and moves with velocity v= v 3 [2ˆx+2ˆy−zˆ]. what is the vector force f on the charge at that instant, in terms of i, q, v, a, and fundamental constants?

The force on the charge is caused by the magnetic field created by the current in the wire. So, first we need to calculate the magnitude and direction of the magnetic field, then we will use this magnetic field to calculate the force on the charge.

Ampere's Law will help us to find the magnetic field created by the wire.

The direction of the B-field can be found by right-hand rule. Point your thumb in the direction of the current. Curl your fingers around the wire. The direction that the four fingers point is the direction of the B-field, it is around the wire.

At the point (0,a,0) the B-field is directed towards +z-direction.

So,

Now, we can calculate the force by using the following formula:

In order to do the cross product, we should use determinant.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
