Two spheres of masses 5.0 kg and 10.0 kg are 0.3 m apart. Calculate the force of attraction between them?
[G = 6.67 X 10-11 Nm2 Kg\(^{-2}\)]
- 3.50 x 10-10N
-
3.71 x 10-8 N
- 3.57 x 10-2N
- 4.00 x 102N
The correct answer is: B
Explanation
The force of attraction between the two spheres is given by F (GM1 M2)/r2 = (6.67X 10-11 X5X10)/(0.3)2
= 3.71 X 10-8N.
