A blue sphere and a red sphere with the same diameter are released from rest at the top of a ramp. The red sphere takes a longer time to reach the bottom of the ramp. The spheres are then rolled off a horizontal table at the same time with the same speed and fall freely to the floor. Which sphere reaches the floor first?
The red sphere
The blue Sphere
The sphere with the greater mass
Neither; the spheres reach the floor at the same time.

Answer:
For free fall, i.e., where any resistive force, like air resistance, any two objects dropped from the same height take the same time to fall under the acceleration due to gravity.
Hence, correct option is : Neither; the spheres take the same time to reach the floor.
