Q. A box of mass 2 kg is lifted diagonally from point A to point B as shown in the given figure. Given that the acceleration due to gravity is 10 m s - 2 , what is the gravitational potential energy gained by the box?


(A) 20 J
(B) 60 J
(C) 80 J
(D) 100 J

Dear Student,potential energy=m×g×hm= massg= acceleration due to gravityh= heightPotential energy at point A=2×10×0=0JPotential Energy at B =2×10×3=60JSo gain in potential energy =60-0=60JRegards
