A body of mass 20kg is transferred from earth (grams=weight newton kg) to another planet where G=2 Newton kg,
1.Wat is the mass on earth?
2.wat is the wieght on earth?
3.wat is the mass on the other planet?
4.wat is the weight on the other planet?

I think you meant to write that "g" on the other planet is 2 Newtons PER kg (which is the same as 2 m/s^2). In physics, the capital letter G is reserved for something else.
1. The mass m is always the same
2. weight = m g, where g = 9.8 m/s^2
3. See 1
4. m g', where g' is your "G". 
i don't understand cud u make it easier
