PhysicsGravitationJEE Main 2014

The gravitational field in a region is given by N . The change in the gravitational potential energy of a particle of mass 2 kg when it is taken from the origin to a point (7 m, −3 m) is

Answer: (3)

Solution

For a uniform field the potential energy change is \vec\vec$ r = -2[(5)(7) + (12)(-3)] = -2(35 -
