PLZ HELP FAST! Which graph BEST shows the relationship of kinetic energy to potential energy as a book sits on the edge of a desk?

Answer:
both energy will remain constant and potential energy must be more than the kinetic energy of the block
So correct Graph will be
A) option
Explanation:
As we know that kinetic energy of the block is given as
[tex]K = \frac{1}{2}mv^2[/tex]
potential energy is given as
[tex]U = mgh[/tex]
so when a block is stationary at the surface of table so due to height of the table the potential energy of the block is given as
[tex]U = mgh[/tex]
but as we know that the speed of the block is zero
so kinetic energy must be
[tex]K = 0[/tex]
so here in the graph both energy will remain constant and potential energy must be more than the kinetic energy of the block
