Suppose a small ball has charge -3.8 PC is located at the origin, and a second small ball has charge 8.0 PC is located along the x-axis at +7.5 cm. if you need more help, try this (a) What is the x-component of the force on the ball at the origin? Be sure to use the correct sign to represent the direction of the component, for "to the right",- for "to the left. 46 64 N (b) What is the x-component of the force on the ball located at 7.5 cm? 4864N (c) Suppose that the second ball at 7.5 cm has charge -8 PC. In this case, what is the x-component of the force on the ball at the origin? (d) The ball is small if its diameter is much less than the separation of the two bats. In this case a ball with diameter 1 mm would be considered small. Such a ball made of ordinary materials would have a mass of no more than 0.01 g. What would the magnitude of the gravitational force of the earth be on such a ball? (Compare the electric and gravitational forces and you can see why we usually can ignore gravity when electric forces are present.)

Figure is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, which is surrounded by an outer conductor, which is surrounded by another rubber layer. In a particular application, the current in the inner conductor I 2 is 6.00 A out of the page and the current in the outer conductor I 1 is 2.00 A into the page. Assume that l = 1.80 mm. Determine the magnitude and direction (upward or downward of the page) of the magnetic field at point b. (Choose upward of the page as the positive y-direction and express the magnetic field by using the sign of the result, which must be in µT and without decimals. That means if you get a result of a 922 and the direction of the field is upward of the page, just type 922 or if you find the direction of the field as downward of the page, just tpe -922 in the answer box. Maximum of 2% error is accepted in your answer. Take vacuum permeability µ 0 = 4π x 10 -7 T /A 2 and π = 3.14.)
