Can I use the r^2 = kq/E as the position equation?

v=vi + a (delta t) For this the final velocity is the same as the starting velocity and the starting position is the same as the starting position. Shouldn't the equation read (v-vi)/a = delta t , for the above equation?

F = qE Acceleration in this case is negative acceleration = (mass) (-force) it would be a constant deceleration

A proton moving to the right at 6.2 × 10^5 ms-1 enters a region where there is an electric field of 62 kNC-1 directed to the left. Describe qualitatively the motion of the proton in this filed. What is the time taken by the proton to come back to the point where it entered the field? I...
