A particle of mass 10 g is kept on the surface of a uniform sphere of mass 100 kg and radius 10 cm. Find the work done against the gravitational force between them to take the particle far away from the sphere.

• A

  $13.34\times {10}^{-10}\mathrm{J}$

• B

  $3.33\times {10}^{-10}\mathrm{J}$

• C

  $6.67\times {10}^{-9}\mathrm{J}$

• D

  $6.67\times {10}^{-10}\mathrm{J}$
