In two different situations a proton is released between the plates of a charged capacitor (uniform E-field). In the first situation, it is released with some initial velocity and travels from position 1 to position 2. In the second situation, it is released with some initial velocity and travels from position 1 to position 3. In both situations the initial speed is the same.
