Answer:
1438.4 N
Explanation:
Applying,
F = kqq'/r²................... Equation 1
Where F = Electrostatic force on the balloons, k = coulomb's constant, q = charge on the first balloon, q' = charge on the second balloon, r = distance between the two ballons.
From the question,
Given: q = q' = 4.0×10⁻⁵ C, r = 0.1 m
Constant: k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( 4.0×10⁻⁵×4.0×10⁻⁵×8.99×10⁹)/0.1²
F = 14.384/0.01
F = 1438.4 N
