Answer 1

LET THE MASS OF OBJECT BE m AND HEIGHT BE h
GIVEN POTENTIAL ENERGY =200
                      m×g×h=200
                              m=$\frac{200}{hg}$...........1
mow when it is raised to height h/4
then potential energy=m×g×h/4
                              =$\frac{200}{hg}$x$\frac{h}{4}$×g
                              =50
