An electron travels through a magnetic field with a strength of 3.90 T and is traveling at a speed of 5.83x107 m/s. What is the z-component of the force on the electron as shown in the figure? H? In the figure provided, an antiproton (same properties as a proton except that q = -e) is moving in through electric and magnetic fields. If B = 2.01 T, E = 3.61x103 V/m and v = 139 m/s, what are the magnitude and direction of the antiproton's acceleration at this instant? Magnitude: Direction: Down 0 Up 0 Left 0 Right The figure provided shows a cross section through three long wires with equal currents and a linear mass density p = 50 g/m. The lower two wires are a distance d = 4 cm apart and are attached to a table. What current will allow the upper wire to float so as to form an equilateral triangle with the lower wires? Answer: Using a vacuum chamber of diameter 66.0 cm you want to create a cyclotron that accelerates protons to 26.0 % of the speed of light. What strength of magnetic eld is required in order for this to work? Magnitude
