Dynamics Physics help urgent

Homework Statement

Sara wonders what the normal force on her 1.0 kg water bottle would be if she tries to lift it with 4.0 N (she used a Newton spring scale to measure her applied force). What is the bottle's acceleration?

Homework Equations

Fg = mg

The Attempt at a Solution

I found Fg which is 9.8 N downwards.
Not sure what to do after this.
Any help, please?
