Answer: 1.024 N
Explanation:
Step 1:
Using Coulomb's law: F=kQ1Q2/d^2
We can rearrange the terms to get :
kQ1Q2=Fxr^2
Substituting: kQ1Q2=0.0224N x (1.63m)^2
Thus kQ1Q2=0.0595
We know that this value will not change when the balls are brought closer together.
Step 2:
Change from cm to m : 1cm=0.01m
24cm=0.24 m
Substitute into the new distance and the calculated value for kQ1Q2 into the coulomb law formula to calculate the new force
F=kQ1Q2/d^2=0.059/(0.24)^2
F=1.024N
