Answer:
q₁ = q₂ = Q = 14.8 pC
Explanation:
Given that
q₁ = q₂ = Q = ?
Distance between charges = r =7.3 cm = 0.073 m
Combined electric field = E₁ + E₂ = E = 50 N/C
Using formula

Rearranging for Q


The earth has an atmosphere that disintegrates most meteorites that make craters, unlike the moon, which has no atmosphere and nothing to protect it from meteorites
