Question

What is the mass of the body that weighs 1N at a place ​

Answer 1

Answer:

weight(Newton)=mass(kg) × acceleration due to gravity (9.8m/s² in this case)

Explanation:

1= mass × 9.8

mass = 1÷9.8=0.102 kg = 102 grams

Answer 2

A body of weight 1N is placed at the surface of the earth, which is assumed to be a perfect sphere of radius 6400km . It is taken to a height of 600km , the weight of the body, in N , would be :
