Answer:
6 x 10²⁵ N
Explanation:
F(electrostatics) = kq₁q₂/r²
Here, q₁ = 2 x 10⁷ & q₂ = 3 x 10⁷
r = 30 cm = (30/100) m = 0.3 m
∴ F = kq₁q₂/r²
= (9 x 10⁹)(2 x 10⁷)(3 x 10⁷)/(0.3)²
= (9 x 2 x 3 x 10²³)/(0.09)
= 6 x 10²⁵ N
Note that if q₁ = 2 x 10⁻⁷ & q₂ = 3 x 10⁻⁷
answer is 6 x 10⁻³ N following the same procedure.
