  V1 / V2 = M2 / M1

  V1 / V2 = M1 / M2

  V1 = V2

  V1 / V2 = (M2 / M1)2

2.

Consider a hole drilled into the Earth and an object placed at the bottom of the hole (point P) as shown in the figure. The gravitational force of attraction on the object will be due to

  region 1 and a portion of region 2

  region 1

  regions 1 and 2

  region 2

3.
