Inserting the values
Conclusion:
Thus, the magnetic field comes out to be .
Answer:
8.1 N/49 N=0.1653 which means 16.53% of the weight of the object on Earth.
Explanation:
On the Moon, where the gravitational constant is 1.62 , the weight of the 5 kg object will be:
Where the answer is in Newtons (N) since all quantities are given in the SI system.
On Earth, on the other hand, the weight of the object is:
Therefore the object's weight on the Moon compared to that on Earth will be:
That is, 16.53% of the weight the object has on Earth.
