A long straight wire carries a current of 51.3 A. An electron, traveling at 1.00 × 107 m/s, is 4.70 cm from the wire. What force acts on the electron if the electron’s velocity is directed toward the wire? If the direction of force is perpendicular to the current, enter a negative value.

9.  A helium nucleus (2 protons, 2 neutrons) is traveling at a velocity of 8.73 x 10^6 m/s a distance of 4.40 cm away from a wire carrying a current of 4.52 A. The helium nucleus is traveling in a direction parallel to the current in the wire. How much acceleration does the helium nucleus experience due to the magnetic force from the current in the wire?     8.59E+09 m/s^2     2.58E+09 m/s^2     1.12E+10 m/s^2     1.55E+10 m/s^2

A helium nucleus (2 protons, 2 neutrons) is traveling at a velocity of 5.27 x 10^6 m/s a distance of 4.88 cm away from a wire carrying a current of 3.01 A. The helium nucleus is traveling in a direction parallel to the current in the wire. How much acceleration does the helium nucleus experience due to the magnetic force from the current in the wire?

Two parallel wires are 14cm apart. One carries a current of 2.3A, while the other carries a current of 5.4A in the same direction. What is the magnitude of the force per unit length that one wire exerts on the other?
