Question

anonymous · Answer

just multiply! 3.50 Newton per kg. how much for 10 kg?

anonymous · Answer

what am i multiplying? 3.50x10?

anonymous · Answer

yes

anonymous · Answer

the gravitational field is 3.5N/kg .. look at the unit.. what does it say?? 

field = 3.5N/kg = "the field would put a force of 3.5N for 1 kg of mass"

thats the meaning.. hence 1kg ---- exp 3.5N of force
                                      10kg -----exp ?

cross multiply .. thats how you work with force fields!

The constant in the question could be described as the local gravitational field  - on Earth at around sea level we are used to the constant having a value of 9.8ms-2 or 9.8N/kg.
