The magnitude of the charge on each object is 3.4 μC.
What is electrostatic force?
The electrostatic force F between two charged objects placed distance apart is directly proportional to the product of the magnitude of charges and inversely proportional to the square of the distance between them.
F = kq₁q₂/r²
where k = 9 x 10⁹ N.m²/C²
Given is the identical charge q₁ = q₂ =q, distance r =16.9cm =0.169m and the force F = 3.62N.
Substitute the values, we get
3.62 = 9 x 10⁹x q² / (0.169)²
q = 3.3894 x 10⁻⁶ C
q = 3.4 μC
Thus, the charge on each object is 3.4 μC.
