An electron passes through a point 3.89 cm from a long straight wire as it moves at 33.9% of the speed of light perpendicularly toward the wire. At that moment a switch is flipped, causing a current of 14.7 A to flow in the wire. Find the magnitude of the electron's acceleration a at that moment.

A long, straight wire lies on a horizontal table and carries a current of 1.20 µA. In a vacuum, a proton moves parallel to the wire (opposite the current) with a constant velocity of 2.30 x 10^4 m/s at a distance d above the wire. Determine the value of d.

A coil with the radius of 20 cm has 10 turns and carries a current of 4 A. A charged particle whose charge equals 60 µ C moves at 1500 m/s through the center of the coil at an angle of 300 to the axis. Compute the magnitude of the force exerted on the particle.

A particle with charge 1.602 × 10-19 C in a magnetic field of 3.58 T travels in a circle of radius 3.14 m at a speed of 9.95 m/s. What is the particle's mass? Answer in units of kg.

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 metal strip 6.70 cm long, 0.850 cm wide, and 0.880 mm thick moves with constant velocity in the positive y direction through a uniform magnetic field B = 2.30 mT that is directed in the negative z direction. A potential difference of 4.60 μV is measured across the width of the strip. What is the magnitude of the velocity v of the strip?

For this question, we have to consider an experimental setup where charged particles (electrons or protons) are first accelerated by an electric field and then injected into a region of constant magnetic field with a field strength of 0.55 T. What is the potential difference, in volts, required to accelerate electrons to a speed of 5.8 * 10^(7) ? Also what is the radius of curvature, in meters, of the path of a proton accelerated through this same potential after the proton crosses into the region with the magnetic field?  This is not a graded question

A helium nucleus (2 protons, 2 neutrons) is traveling at a velocity of 5.06 x 10^6 m/s a distance of 4.93 cm away from a wire carrying a current of 2.81 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? 1.66E+09 m/s^2 3.86E+09 m/s^2 4.97E+09 m/s^2 2.76E+09 m/s^2

A velocity selector is tuned to allow an electron with a speed of 280279 m/s through with no deflection. It used a magnetic field of 7.8 mT. What is the magnitude of the electric field (in V/m) being used?

a proton (mass 1.67e-27 kg, charge 1.6e-19) with a constant speed of 3.1 x 10^4 is traveling in a vacuum chamber at a distance 1.90 cm above a long horizontal wire that carries a current I. It moves in a direction to the wire (opposite the current). Determine the value of I
