Question

To conduct an experiment, a scientist has two metal spheres made to have the same diameter and surface texture. Sphere A is hollow and has a mass of m, while sphere B is solid and has a mass of 4m. The scientist drops the two spheres at the same time from a tall structure. As the two spheres fall through the air, which sphere has the greater acceleration after 1 second?

A) Sphere A. B) Sphere B C) They have the same acceleration. D) There is not enough information to tell

Which one will land first Sphere A, Sphere B, or both land at the same time?

Explanation / Answer

a)

C) They have the same acceleration. is the answer

Since Both Spheres A and B are falling from a height i.e free falling ,they have same accelration due to gravity since acceleration due to gravity g=9.8 m/s2 is same irrespective of mass ,diameter and shape after 1 second .

b)

Sphere B is the answer.

Since Sphere B exerts more force due to weight i.e FB=4mg Compared to Sphere FA=mg.due to free fall .
