A point mass of (10 ~kg ) is placed at the centre of earth. The weight of the point mass is

Options

  1. Azero
  2. B(98 ~N )
  3. C(49 ~N )
  4. D(10 ~N )

Correct answer

A. zero

Step-by-step solution

At the centre of earth, gravitational acceleration (g ) is zero. Hence, weight of point mass, (w=m g=10 0=0 )
