Answer:
A. 0.015 newtons
Explanation:
The electric force of two charged objects will be directly proportional to the charge of both objects. The force also inversely proportional to the square of the distance. The distance of the object is changed 4 times longer than before. In short, the force will be 4^2= 16 times lower than before.
The calculation will be:
F= [tex]\frac{kQ1Q2}{r^{2} }[/tex]
F1/F2= [tex]\frac{kQ1Q2}{r^{2} }[/tex]/ [tex]\frac{kQ1Q2}{4r^{2} }[/tex]
0.24N/F2= [tex]\frac{16r^{2} }{r^{2} }[/tex]
0.24N= 16F2
F2= 0.24N/ 16= 0.015N
