Question

what is the mass of a body that weight 1 Newton on earth​

Answer 1

In physics the standard unit of weight is Newton, and the standard unit of mass is the kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N.

Answer 2

Explanation:

weight = mass * acceleration due to the gravity

and

mass= weight /acceleration due to the gravity

mass= 1000/ 9.8. (1N=1000dyne)

mass=102g
