Question

Determine the electrical force of attraction between two balloons with separate charges of +3.5 × 10-8 C and -2.9 × 10-8 C when separated a distance of 0.65 m.

Answer 1

Answer:

The electrical force of attraction between the balloons is $2.16\times 10^{-5}\ N$.

Explanation:

Given that,

Charge 1, $q_1=+3.5\times 10^{-8}\ C$

Charge 2, $q_2=-2.9\times 10^{-8}\ C$

Distance between the charges, d = 0.65 m

We need to find the electrical force of attraction between two balloons. It is given by the formula as :

$F=k\dfrac{q_1q_2}{d^2}\\\\F=9\times 10^9\times \dfrac{3.5\times 10^{-8}\times 2.9\times 10^{-8}}{(0.65)^2}\\\\F=2.16\times 10^{-5}\ N$

So, the electrical force of attraction between the balloons is $2.16\times 10^{-5}\ N$. Hence, this is the required solution.
