A person brings a mass `2kg` from `A` to `B`. The increase in kinetic energy of mass is `4J` and work done by the person on the mass is `-10J`. The potential difference between `B` and `A` is ......`J//kg`

A person brings a mass of 1 kg from infinity to a point . Initally the mass was at rest but it moves at a speed of 2 ms^-1 as it reaches A. The work done by the person on the mass is -3J. The potential at A is
