In a certain region of space, a uniform electric field has a magnitude of 4.30 x 104 n/c and points in the positive x direction. find the magnitude and direction of the force this field exerts on a charge of +6.80 μc.

Aproton is projected toward a fixed nucleus of charge +ze with velocity vo. initially the two particles are very far apart. when the proton is a distance r from the nucleus its velocity has decreased to 1/2vo. how far from the nucleus will the proton be when its velocity has dropped to 1/4vo?
