Question

Two spheres each of mass 10 power 5 kg and radius 10m are kept in contact. Find the force of gravitation acting between them.

Answer 1

Answer: 10 power 8 Newton

Explanation:

G=m1m2/r^2

10^5 10^5/ 10^2

10^10 /10^2

10^8 N

Answer 2

Answer:

6.67 X10 ^-3

Explanation:

F= G Mm/d^2  

  = 6.67  X 10 ^-11  X 10^5 X 10 ^ 5 / 20 ^ 2

   = 1.67 X10 ^-3
