Answer:
What is the force between two small charged spheres having charges of 2 x 10-7 C and 3 x 10-7 C placed 30 cm apart in air? Hence, force between the two small charged spheres is 6 × 10 - 3 N. The charges are of same nature. Hence, force between them will be repulsive.

Hey Buddy here's ur answer
According to Coulombs law,
F = KQ₁Q₂/r²
where , Q₁ and Q₂ are charges and r is the separation between charges .
Given, Q₁ = 2 × 10⁻⁷C
Q₂ = 3 × 10⁻⁷C
r = 30cm = 0.3 m
K = 9 × 10⁹ Nm²/C²
∴ F = 9 × 10⁹ × 2 × 10⁻⁷ × 3 × 10⁻⁷/(0.3)²
= 9 × 10⁹ × 6 × 10⁻¹⁴/0.09
= 6 × 10⁻³N
Hence, force = 6 × 10⁻³ N
