Question 1 N Point on bisecting line Charge Q + + + + + + + + + X What is the electric potential at the point on the axis which is at z= 3.60 m. The length of the rod is _ = 1.20 m and the charge on the rod is Q = 7.60 nC. Question 2 *+ + + + + + + + A parallel-plate capacitor is formed of two 19.0 cm x 19.0 cm plates and spaced & = 2.50 cm apart. The plates are charged to 1:3.60 nC. If an electron is shot through a very small hole in the positive plate, as shown in the figure. What is the slowest speed the electron can have if it is to reach the negative plate? Magnitude
