Answer:

Step-by-step explanation:

Given:

r₂ = 3·r₁

________

F₂ / F₁ - ?

According to Coulomb's law:

F₁ = k·q₁·q₂ / r₁²

F₂ = k·q₁·q₂ / r₂²

F₂ / F₁ = (r₁ / r₂)²

F₂ / F₁ = ( r₁ / (3·r₁)² = (1 / 3)² = 1 / 9

Strength will decrease by 9 times

Here is your Answer:-

If the distance separating the objects is tripled, then what is the new force? Explanation: -The electrostatic force is inversely related to the square of the separation distance. So if d is three times larger, then F is nine times smaller – that is, one-ninth the original value.
