Answer:

450 × 10 ⁻⁹ N

Explanation:

From the given:

The direction of force is;

tan \ \theta = \dfrac{2}{2}

\theta =tan  ^{-1} (1)

\theta = 45^0

Hence, the angle is 45° counterclockwise from + x-axis

However;

the magnitude of the force is:

F = \dfrac{kq_1q_2}{r^2}

F = \dfrac{(9*10^9 \ Nm^2/C^2 )*( 40 * 10^{-9} \ C ) * (10*10^{-9} \ C)}{(\sqrt{8})^2}

F = 450 \times 10^{-9} \ N

Kaylis [27]

Answer:

Rubber is an insulator.

Explanation:

Rubber is an insulator. Electricity will always travel "the path of least resistance." Rubber has a very high resistance, so electricity will go somewhere else to find ground.
