Question 1 -0 +0 Charge +Q +8.90 nC is unt rrnhy distributed along the right half of a thin rod bent nto a seno le of radius R-8.70 cm, whǐ charge-q = 90 nC is u f miy dstributed along the left half of the rod, as shown in the figure. What is the magritude and direction of the electric field at point P, the centre of the circle? Magnitude: Oirection, given as an angle measured counterclockwise from the positive x axis: Question 2 Two parallel plates, each charged equally and oppositely to the other, are separated by 3 SS。。cm A proton , et go hom rest at ne po itve plain otse ind at thr in e me at electron is let go from rest at the negative plate's surface. What is the distance between the negative plate and the point where the proton and the electron go by each other?
