The mass of earth on the basis of Newton's Law of Gravitation is given by:
Correct answer: C. M = 5.98 x 10^24 kg
- A. M = 9.1 x 10^-31 kg
- B. M = 1.6027 x 10^-27 kg
- C. M = 5.98 x 10^24 kg
- D. M = 6.02 x 10^23 kg
- E. M = 3 x 10^3 kg
Explanation
By equating Newton's second law with his law of universal gravitation, and inputting for the acceleration the experimentally verified value of 9.8 m/s2, the mass of the earth is calculated to be 5.98 x 10^24 kg . Since it is numerically derivated so it could have only one answer.
