Answer:
F=-6.966N
Step-by-step explanation:
The formula for calculating the force of attraction between the two charged object is given as
[tex]F = k_e \frac{Q_1Q_2}{ {d}^{2} } [/tex]
Where k_e is the coulomb constant then Q1 and Q2 are the charges of the charge objects and d is the distance between them from their centers.
[tex]F = \frac{Q_1Q_2}{4\pi\epsilon_o {d}^{2} } [/tex]
putting in the values,
[tex]F = \frac{(7 \times {10}^{ - 6})( - 3.2 \times {10}^{ - 6}) }{4\pi\epsilon_o {0.17}^{2} } = - 6.966N[/tex]
the negative sign means that is a force is between unlike charges.
