A long, straight wire lies along the ¤-axis and carries current I = 60.0 A in the +x-direction. A small particle with mass 3.00 x 10-6 kg and charge 8.00 × 10-3 C is traveling in the vicinity of the wire. At an instant when the particle is on the y-axis at y = 7.00 cm, its acceleration has components a, = -5.00 × 103 m/s² and a, = +9.00 × 10³ m/s². Part A At that instant what are the z- and y-components of the velocity of the particle?

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?

A wire is held horizontally in a vacuum chamber, and carries a current of 1.40 µA. A proton is traveling in a direction parallel to the wire (opposite the current) with a constant speed of 2.60 ✕ 104 m/s at a distance d above the wire. Ignoring the magnetic field due to the Earth, determine the value of d (in cm).       What If? At what distance, d (in m) would an electron moving with the same speed as the proton moves parallel to the wire?     What direction would the electron have to move?   In the same direction as the proton. In the opposite direction as the proton.     There is too little information to determine the direction.

Problem 13: Suppose the starter cable of a car is carrying 130 A of current. Assume this cable is long and straight. How many meters from the cable must you be to experience a field less than the Earth's (5.00 × 10-5 T)? r =
