A)It takes the lighter object 5 times longer to reach the bottom of the ramp than the heavier.
B)It takes the lighter object 10 times longer to reach the bottom of the ramp than the heavier.
C)It takes the heavier object 5 times longer to reach the bottom of the ramp than the lighter.
D)It takes the heavier object 10 times longer to reach the bottom of the ramp than the lighter.
E)The two objects reach the bottom of the ramp at exactly the same time.

The masses of the objects do not affect their acceleration due to gravity, which is the same for both of them. Therefore, they will both reach the bottom of the ramp at the same time, regardless of their individual masses. This is in accordance with the principle of equivalence, which states that inertial mass and gravitational mass are the same.
