Could i please get some help with this, it would mean a lot, thank you.

Question 1 Glass In the gure provided, a glass sphere is suspended in air by a thread. If the sphere is positively charged and the north pole of a bar magnet is brought near the sphere, which of the following is true? 0 The sphere is unaffected by the magnet. O The sphere is repelled by the magnet. O The sphere is attracted to the magnet. Question 2 V . . . In the figure provided, for the charged particle entering the magnetic field, what is the initial direction of deflection? O Up O Left O Down O RightQuestion 3 + V into page What is the direction of the magnetic field in the figure provided? O In the plane of the page, 45 counterclockwise from straight down. O In the plane of the page, 45 counterclockwise from straight up. O In the plane of the page, 45 clockwise from straight up. O In the plane of the page, 45 clockwise from straight down.Question 4 Evaluate the cross product 1 X 3 of the two vectors above. They are separated by an angle of 70.0\" and have magnitudes given by: Vector A: 10.0 Vector B: 5.00 O (47.0, into the screen) O (47.0, out of the screen) O (17.1, out ofthe screen) 0 (17.1, into the screen) 5. (Knight Problem 29.27) An electron moves in the magnetic field B = 0.50i T with a speed of 1.0 x 10' m/s in the direc- tions shown in FIGURE EX29.27. For each, what is mag- netic force F on the electron? Give your answers in compo- nent form. Answer: a. 8.0x10- *j N. b. 5.7x10 (-j-k) N.](a) (b) 450 FIGURE EX29.27 6. (Knight Problem 29.31) The microwaves in a microwave oven are produced in a special tube called a magnetron. The elec- trons orbit the magnetic field at 2.4 GHz, and as they do so they emit 2.4 GHz electromagnetic waves. a. What is the magnetic field strength? [Answer: 86 mT.] b. If the maximum diameter of the electron orbit before the electron hits the wall of the tube is 2.5 cm, what is the maximum electron kinetic energy? [Answer: 1.62 x 10-14 J.] 7.
