Answer #1

For this question Work- Energy theorem is to be applied. According to this theorem, work done by the force is equal to the change in kinetic energy.

Since here the charge is slow down when it go through the potential difference, it can be concluded that charge is going towards higher potential from lower, as it is positive charge, hence it will slow down.

Solution is attached here with the scanned sheet.
