A solid uniform sphere of mass M and radius R with centre C is isolated in space. If in the sphere a cavity of radius R 2 with centre C₁ is made, then the potential at a point P at a distance of 2 R from centre C is

Options

  1. A- 2 G M 5 R
  2. B- 2 G M 5 R
  3. C=- 2 G M 5 R
  4. DNone of these.

Correct answer

C. =- 2 G M 5 R

Step-by-step solution

-G M 2 R + G M 4 5 R 2 =- 2 G M 5 R
