Answer:-
Phosphorus
Explanation:-
In the third period among the elements given, phosphorus is at the most right side among them in the periodic table.
We know that as we go from left to right in the periodic table, the atomic size decreases due to the increase in nuclear charge.
Hence phosphorus is the smallest among them
Answer:
+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
