Question: Charge + = +8.10 nC is uniformly distributed along the right half of a thin rod bent into a semicirle of radius R =

Charge + = +8.10 nC is uniformly distributed along the right half of a thin rod bent into a semicirle of radius R =

Charge + = +8.10 nC is uniformly distributed along the right half of a thin rod bent into a semicirle of radius R = 4.60 cm, while charge -Q = -8.10 nC is uniformly distributed along the left half of the rod, as shown in the figure. What is the magnitude of the electric field at point P, the centre of the circle? Magnitude: P R +Q
