Answer:
The electrical force on 2nd charge (3 Q) will also be equal to F.
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.
<u>Therefore, the electrical force on 2nd charge (3 Q) will also be equal to F.</u>
