In a long straight wire, what current is required to exert a 1.0μN force on a 1.0μC charge moving at 1.5×106m/s parallel to the wire at a distance of 0.35m from the wire?

Current in the wire is given as

Explanation:

magnetic field due to long current carrying wire is given as

so we have magnetic force on moving charge is given as

so we have

so we have

measure their densities same density, same sub

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
