Question

Two balloons are charged with an identical quantity and type of charge: 0.004 C. They are held apart at a separation distance of 5m. Determine the magnitude of the electrical force of repulsion between them.

Answer 1

The answer to your question is F = 28800 N

Step-by-step explanation:

Data

q₁ = q₂ = 0.004 C

distance = r = 5 m

k = 9x 10⁹ C

Force = F

Formula

F = k q₁ q₂ / r²

-Substitution

F = (9 x 10⁹)(0.004)(0.004) / (5)²

-Simplification

F = 144000 / 25

-Result

F = 28800 N

-Conclusion

The force of repulsion between these balloons is 28800 N
