A -91.0 nC charge is placed at (-0.600 m, 0) and a +37.0 nC charge is placed at (0.600 m, 0).

a) Find the force on the +37.0 nC charge. b) Find the electric field at (0, -0.800 m). c) If a proton is placed at rest at (0, -0.800 m), find its acceleration. d) If a neutron is placed at rest at (0, -0.800 m), find its acceleration.
