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 mas was at rest but it moves at a speed of 2 ms^-1 as it reaches A. The work done by the perosn on the mass is -3J. The potential at A is

A person brings a mass of 1 kg from infinty to a point A . Initially, the mass was at rest but it moves at a speed of 3 m//s as it reaches A . The work done by the person on the mass is - 5.5 J . The gravitational potential at A is

Gravitational force is a conservation and medium independent force. Its nature is attractive. Gravitational field intensity and gravitational potential gives information about gravitational fied in vector and scaler form respectively. Actually gravitational fied intensity is equal to the negative of the negative of teh potential gradient. potential energy is defined for only conservation force. it is also equal to the total energy in escaping condition. gravitational potential is either negative or zero but can never be positive due to attractive nature of gravitational force. A person brings a mass of 1 kg from infinity to a point A . Initially the mass was at rest but it moves with a speed of 2 m//s as it reaches A . The work done by the person on a mass is -3 J . The potential of A is:
