Answer:
The answer to your question is: q = 1.67 x 10 ⁻⁶ C
Explanation:
Data
q = ? q1 = q2
F = 0.1 N
r = 50 cm = 0.5 m
k = 8.98 x 10 ⁹ Nm²/ C²
Formula
F = kq1q1 / r² = kq² / r²
q² = Fr²/ k
Process
q² = (0.1)(0.5)²/ 8.98 x 10 ⁹ Substitution
q² = 0.025 / 8.98 x 10 ⁹
q² = 2.78 x 10⁻¹²
q = 1.67 x 10 ⁻⁶ C
