If charge on only one object is tripled, determine the new force between them:

+3·F

Explanation:

The number of objects in the given system = 2 objects

The charge on each object are; q₁ = -Q, q₂ = -Q

The force acting between the objects = +F

The distance between the objects = 2·d

The formula for the force acting between two charged particles is given as follows;

Therefore, we get;

By tripling the charge, q₁, on the first object, we get;

q₂ = 3 × (-Q)

Therefore, the new force between them, F₂ = +3·F
