BEFORE YOU BEGIN: Take your ID number and add to it as shown. Let's use an example where my ID number is 123456789: 123456789 + 111111111 = ABCDEFGHI My new calculated number is now ABCDEGHI. (Of course, show your working.) My ID is 816004694. Therefore, 816004694 + 111111111 = 927115805 Utilize the numbers from your calculated number as required in the questions below. QUESTIONS: 1. An alpha particle, with velocity of magnitude 560 m/s, travels horizontally into a region of space in which there is an upward-directed uniform electric field of magnitude 56 N/C. a) State and explain what happens to the alpha particle on entering the region of space with the uniform electric field. (3 marks) A magnetic field of 0.9F tesla is now introduced into the region of space. (There are now two fields - an electric field and a magnetic field - present.) Determine the angle that the magnetic field should make with the alpha particle's velocity vector to cause the alpha particle to pass through the region of space undeflected. Clearly explain your reasoning in answering this question. (Use of equations alone will not result in full marks.) (7 marks) b) The alpha particle is replaced with an electron. (Its velocity vector is the same as that of the alpha particle.) What must be done, if anything, with the electric and/or magnetic fields to ensure that the electron also remains undeflected? Clearly justify your response. Include an explanation of what happens to the moving electron in the presence of the electric field and in the presence of the magnetic field. (5 marks)
