Answer:
The electrical force on 2nd charge (3 Q) will also be equal to F.
Step-by-step explanation:
The electrical force between two electrically charged particles is given by the Coulomb's Law. The mathematical formula of Coulomb's Law is as follows:
F = kQ₁Q₂/r²
where,
F = Electrical Force exerted by both particles on each other
k = Coulomb's Constant
Q₁ = Magnitude of 1st Charge = Q
Q₂ = Magnitude of 2nd Charge = 3 Q
r = Distance between the charges
Therefore,
F = k(Q)(3 Q)/r²
F = 3 kQ²/r²
Since, it is clear from the formula that the magnitude of force applied by the first charge on 2nd charge is equal to the force applied by 2nd charge on 1st charge.
Therefore, the electrical force on 2nd charge (3 Q) will also be equal to F.
