Question

A particle of mass 10g is kept on the surface of a uniform sphere of mass 100 kg and radius 10 cm Find the work to be done aginst the gravitational force between them to take the particle is away from the sphere (G=6.67cross times 10 to the power of negative 4 end exponent SI unit)

  1. 6.67cross times 10 to the power of negative 9 end exponentJ
  2. 6.67cross times 10 to the power of negative 10 end exponent
  3. 13.34cross times 10 to the power of negative 10 end exponentJ
  4. 3.33cross times 10 to the power of negative 10 end exponentJ

The correct answer is: 6.67cross times 10 to the power of negative 10 end exponent
