Problem

The gravitational field in a region is given by g⃗=5N/kgi^+12N/kgj^\vec{g} = 5\text{N/kg}\hat{i} + 12\text{N/kg}\hat{j} . The change in the gravitational potential energy of a particle of mass 1 kg when it is taken from the origin to a point (7 m, -3 m) is: (1) 71 J (2) 1358J13\sqrt{58}\text{J} (3) -71 J (4) 1 J
