answer questions 10-12

Shortcuts 010 (part 1 of 3) 10.0 points A charge of 8 uC is at the origin. What is the magnitude of the electric field on the ax axis at a = 7 m? The Coulomb constant is 8.98755 x 109 N - m2/C2 Answer in units of N/C. 2 011 (part 2 of 3) 10.0 points What is the magnitude of the electric field on is. the x axis at * = -10 m? Answer in units of N/C. 3 012 (part 3 of 3) 10.0 points Sketch the function Ex versus x for both posi- tive and negative values of x. Remember that Ex is negative when E points in the negative na r direction. here it is 500 250 5 0 Ex (N/C) -250 ectric nt p. -500 6. -2 0 2 x (m) printer flected field to
