Answer 1

b. 1,35×10^10

Answer 2

The question is related to Coulomb's Law, which describes the force between two point charges. Coulomb's Law is given by the formula:

\[F = k \frac{|q_1 q_2|}{r^2}\]

where:
- \(F\) is the force between the charges,
- \(k\) is Coulomb's constant (\(9 \times 10^9 \, \text{Nm}^2/\text{C}^2\)),
- \(q_1\) and \(q_2\) are the magnitudes of the two charges,
- \(r\) is the distance between the charges.

Given in the question:
- \(q_1 = 60 \, \text{Coulombs}\),
- \(q_2 = 40 \, \text{Coulombs}\),
- \(r = 40 \, \text{cm} = 0.4 \, \text{meters}\) (conversion from cm to meters is necessary as Coulomb's constant is in meter units).

Substituting these values into Coulomb's Law formula:

\[F = 9 \times 10^9 \times \frac{|60 \times 40|}{0.4^2}\]

Calculating this will give us the force in Newtons.
