If the gravitational force between two identical masses m, is 6.67 x 10^-11 N, when they are 1 m apart, then the value of each mass will be:
Correct answer: B. 1 kg
- A. 2 kg
- B. 1 kg
- C. 0.5 kg
- D. 4 kg
Explanation
F=Gmm/R2 As F= 6.67 x10-11 N, it can be seen that F=G and this is only possible when the product of masses is equal to 1.This can also be seen by adding these values to the formula = F=G(1)(1)/12 Hence F=G and the correct option is B.
