Unformatted text preview: Partial Solution Derivations for Capa #2 10) The figure shows the E-field in the plane of two point charges. (Give ALL correct answers, i.e., B, AC, BCD...) QUESTION: A) The magnitude of E is the same at ‘a’ and ‘b’. B) A – charge placed at ‘a’ would move left. C) | Q 1 | is larger than | Q 2 | D) Q 1 and Q 2 have the same sign. E) A + charge at ‘a’ would move left. F) Q 1 is positive. ANSWER: A) False - The field lines are more dense at ‘a’. B) False - Positive charges follow the field lines, not negative ones; it would move right. C) True - There are more field lines coming from Q 1 than Q 2 . D) False - The field lines point away from Q 1 and toward Q 2 . E) True - Positive charges follow the field lines. F) True - The field lines point away from it. Remember to give the letters of the correct answers, in this case, CEF. 11) Two point-like particles are placed 35 . 9 cm apart and are given equal and opposite charge. The first particle, of mass 24 . g , has an initial acceleration of 4 . 75 m/s 2 towards the second particle. What is the mass of the second particle if its initial acceleration towards the first is 7 . 20 m/s 2 ?...
