Answer:
8N
Explanation:
coulomb's law is applied in finding the solution to this problem
the law states that "for two point charges separated by a finite distance, the magnitude of force between them id directly proportional to the product of the charges and inversely proportional to the square of the distance between them".
mathematically, F= kq₁q₂/ r²
inital force exerted, F=2N
distance =1m
2=kq₁q₂/ (1)²
2× 1=k × q₁q₂
k=2/q₁q₂
when magnitude of charge is doubled
F¹=kq₁q₂/ r²
new force F¹ =[tex]\frac{2}{q_{1}q_{2} }[/tex] ×[tex]\frac{2q_{1} 2q_{2} }{1^{2} }[/tex]
=2×2×2
=8N
