2. A rod of uniform linear charge density +1.5 x 10-5 C/ m is bent into an arc of radius R = 0.10 m. The arc is placed with its center at the origin of the axis. A proton is placed at point O and held at rest.
a) Determine the magnitude and direction of the force required to keep the proton at rest. (Ignore the effects of gravity)
b) Determine the electric potential at point O.
