A certain bag of groceries has a mass of 10 kilograms and a weight of about..

A. 1N
B. 10N
C. 100N

On which planet? ;)

(I don't want you to answer it, but I want you to think about why I asked).

So should I answer this question or not?

The answer is 100 N because you mulitply 10 kg by 9.8 so u get approx. 100 N. This of course is referring to Earth because the gravitational pull on Earth is 9.8.
