Twо lаrge pаrаllel cоpper plates are 6 . 00 c m apart and оne of the plates carries negative charges with surface charge density - σ and another positive charges with surface charge σ as depicted in Fig. 2. An electron is released from the negative plate at the same time that a proton is released from the positive plate. (a) Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other. After the electron penetrates the positive plate without resistance, it enters a region with a uniform magnetic field directed in the negative z direction and exits 0 . 630 μ C later at point A. The boundary of the uniform magnetic region is shown in Fig. 2. (b) What is the magnitude of the magnetic field in the magnetic region, and (c) what is the magnitude of the electric field between the two copper plates? If the magnitude of the electric field between two copper plates are doubled and the magnitude of the magnetic field remains the same as the one determined in (b), (d) what are the x and y components of the velocity of the electron when it exits the magnetic region? If the magnitude of the electric field remains the same as the one determined in (c) and the magnitude of the magnetic field changes, (e) what is the magnitude of the magnetic field if the electron exits the magnetic region with the same x and y components of velocity? (Note: The mass of an electron is 9 . 11 × 10 - 31 k g , the charge of an electron is - 1 . 60 × 10 - 19 C ; the mass of a proton is 1 . 67 × 10 - 27 k g , the charge of a proton is 1 . 60 × 10 - 19 k g .) f_q18_phys2426.v02.docx

Cоnsider the diаgrаm аbоve. The Trail Listing System is designed fоr people who want to learn about the trails in the area. New trails can be added, and existing trails can be removed. The Trail Listing System has lots of trails. Each trail includes a map, distance, description, and difficulty. Some trails require permits. These trails also include permit type, permit cost, and maximum number of hikers on the permit. A portion of the system includes the following classes. Notice that no methods are listed yet. How do we document the relationship between Trail and PermitTrail?
