Hand written answers with steps for questions 5,6 and 7

5) An electron travelling at 6.00 x 107 m/s [north] enters a 4.00 x 10 T [south] magnetic field. Determine the magnitude of the magnetic force that the electron feels while moving in the magnetic field. Use the following information to answer the next question. A Cu* ion has a mass of 1.06 x 1025 kg. The copper ion is accelerated from rest through a potential difference of 825 V where it exits the parallel plates through a small hole and enters a magnetic field of 0.600 T, as shown in the diagram below. The copper ion travels in path where it either reaches detector 'A', 'B', or 'C'.

Then, a 0.400 T magnetic field bends the ion into a circular path of radius 0.226 m. What is the mass of the ion? Use the following information to answer the next question. A light (approximately massless) frame supports a rectangular conducting wire WXYZ that is balanced horizontally at its midpoint within a 2.0 T magnetic field created by a solenoid, as shown below. Sides WX and YZ are 10.0 cm long and are parallel to the magnetic field within the solenoid. Side XY is 3.5 cm long and is perpendicular to the magnetic field within the solenoid. A 50-g mass hangs from the outside end of the massless frame. 7) Determine magnitude of the current required through the rectangular conducting wire to keep the system in horizontal equilibrium (stationary)
