The electric field on the axis of a uniformly charged ring has magnitude 400 kN/C at a point 6 cm from the ring center. The magnitude 15 cm from the center is 125 kN/C; in both cases the field points away from the ring. a. Find the rings radius b. find the rings charge

Point charge A is on the x-axis at z = -3.00 cm. At x = 1.00 cm on the x-axis its electric field is 2700 N/C. Point charge B is also on the x-axis, at a = 5.00 cm. The absolute magnitude of charge B is twice that of A. Part A Find the magnitude and direction of the total electric field at the origin if both A and B are positive. Express your answer in newtons per coulomb. Enter positive value if the field points in +x-direction and negative value if the field points in -x-direction. Ez = N/C Part B Find the magnitude and direction of the total electric field at the origin if both A and B are negative. Express your answer in newtons per coulomb. Enter positive value if the field points in +x-direction and negative value if the field points in -x-direction. E = N/C

A rod of length l = 5 m, is uniformly charged and has a total charge of 46 nC. What is the magnitude of the electric field (in N/C) at the point 'P' which lies along the axis of the rod and is 4.8 m from the center of the rod? E P
