Consider eight charges q1, q2, q3, q4, q5, q6, q7, q8 of equal magnitude q=35e arranged at equal intervals on a circle with radius R=9×10 -9 m (Keep in in mind that the charge of an electron is negative). And then one of them, q8, is removed from the arrangement and we are left with only 7 charges that are q1, q2, q3, q4, q5, q6, q7. The coordinate of q7 is (0,0,−R). Consider a point P which lies on a point on the axis of the circle at a distance of d=40×10-9 m away as shown in the figure. (The figure on the top represents the 3d visual of the system and the figure on the bottom is the YZ plane.) The three coordinate directions are shown by the i, j, k unit vectors. a) What is the electric field at point P? b) Suppose we put a proton at point P. What is the force on the proton? c) What would be the magnitude of the acceleration of the proton?
