Question
Charging Clarging by frictional contact typically produces satie chap small by wll be to find how fast the objeet would have to move through e local ic objeets, Suppose a small object of mass 2 g has a chano T arati 9 C. Our magnetic field to y produces static charge of s d experience a magnetic force equal to its weight. (Use g-9.81 to gravity.) a 10 T 21. What is the best way to relate F and a? D) Newton's law law law C) Newton's third 22. What is a special case of your previous answer? A) Newton's fourth law B) Newton's first third D) Newton's ewton' C) Newton's law law law 23. Say our small object is moving to the right. According to the is the B-field pointed so that it experiences a magnetic force eg to the right hand rule, which direction equal to its weight? A) Down B) Up D) Right C) Left 24. For a given v, which component of the B-field contributes to F? A) Perpendicular B) Hypotenuse C) Parallel 25. Your answer to the previous question would seem to indicate that D) None A) B) 0' C) 270 D) 180 26. Magnitude of v: A) 2.00E5 m/sB) 1.96E9 m/s 1.96E6 m/s D)-1.96E6 m/s 27. Direction of v: A) Down B) Up C) Left D) Right 28. The direction of v comes from the C) left hand rule. D) use of common sense B) right hand rule. A) vector dot uct 29. Magnetic force is an example of a B) vector dot product. C) vector cross product D) vector tensor product. A) vector operation. 0. What kind of quantity is magnetic force? C) Number B) Scalar D) Tensor A) VectorExplanation / Answer
