본문 EXERCISES Section 26.2 Magnetic Force and Field 17. INTERPRET This problem is about the magnetic force exerted on a moving electron. DEVELOP The magnetic force on a charge q moving with velocity is given by Equation 26.1: The magnitude of is EVALUATE (a) The magnetic field is a minimum when (the magnetic field perpendicular to the velocity). Thus, (b) For the magnetic field is ASSESS The magnetic force on the electron is very tiny. The magnetic field required to produce this force can be compared to the Earth's magnetic field, which is about 1 G. 18. (a) If the magnetic force is the only one of significance acting in this problem, then Thus, (b) Since is perpendicular to the magnetic force on a charged particle changes its direction, but not its speed. 19. INTERPRET In this problem we are asked to find the magnetic force exerted on a moving proton. DEVELOP The magnetic force on a charge q moving with velocity is given by Equation 26.1: The magnitude of is The charge of the proton is EVALUATE (a) When the magnitude of the magnetic force is (b) When the force is (c) When the force is ASSESS The magnetic force is a maximum when and a minimum when 20. An electron, moving perpendicularly to the Earth's magnetic field near the surface, experiences a maximum magnetic force of The weight of an electron near the Earth's surface is a factor of nearly times smaller. 21. INTERPRET This problem is about the speed of a given charge if it is to pass through the velocity selector undeflected. 하고 싶은 말 좀 더 업그레이드하여 자료를 보완하여, 과제물을 꼼꼼하게 정성을 들어 작성했습니다. 위 자료 요약정리 잘되어 있으니 잘 참고하시어 학업에 나날이 발전이 있기를 기원합니다 ^^ 구입자 분의 앞날에 항상 무궁한 발전과 행복과 행운이 깃들기를 홧팅 키워드 단원, 핵심, 레포트답안, 전기파트, 핵심물리학, 물리학
