Question 10
A balloon with a charge of -6.67 x 10-6 C is brought near a metal rod with a
charge of -5.27 x 10-8 C. They are separated by a distance of 0.43 m.
a) What is the electrical force acting on them? (round your answer to the
nearest ten thousandths place, for example 0.1234 or -0.1234)
Please help me

Answer:

0.1707 N

Explanation:

From the question,

Applying Coulombs law

F = kqq'/r²................... Equation 1

Where F = Electric Force, q = First charge, q' = second charge, r = distance between the charges, k = coulomb's constant

Given: q = -6.67×10⁻⁶ C, q' = -5.27×10⁻⁸C, r = 0.43 m

Constant: k = 8.98×10⁹ Nm²/C²

Substitute these values into equation 1

F = [(-6.67×10⁻⁶)(-5.27×10⁻⁸)(8.98×10⁹)]/(0.43)²

F = (315.655×10⁻⁵)/(0.1849)

F = 1707.17×10⁻⁵

F = 1.7072×10⁻²

F = 0.1707 N
