SOLUTION :
F is inversely proportional to squared distance.
=> F = k / d^2
So,
F1 = k / (d1)^2 = 48 N
=> k = 48 (d1)^2
F2 = k / (d2)^2
=> F2 = [48 *(d1)^2] / (d2)^2 = 48 / (d2 / d1)^2 = 48 / 4.4^2 = 2.48 N
Hence, force between charges will be 2.48 N if distance is increased 4.4 times (ANSWER).

Two point charges each experience a 1-N electrostatic force when they are 2 cm apart. If they are moved to a new separation of 8 cm, what is the magnitude of the electric force on each of them
An electric dipole is formed from two charges, ±q, spaced a distance s apart. The distance s is small compared to 10 cm. The dipole is at the origin, and the dipole moment p⃗ points in the y-direction. The electric field strength at the point P:(x,y)=(0cm,10cm) is 320 N/C 1. The two charges, ±q, are spaced a distance s apart. The dipole moment p⃗ is rotated 90∘ so it points in the +x-direction. What is the electric field E⃗ at the point P:(x,y)=(0cm,10cm) ? Give your...
