Answer:
a) 9.0
Explanation:
The force between two point charges, obeys Coulomb's Law, which can be written as follows:
[tex]F =\frac{k*q1*q2}{(r12)^{2} }[/tex]
As it can be seen, if the separation between the charges remains the same, the new value of the force will be directly proportional to the product of the charges.
If both charges are tripled, the mutual force between them will be changed in a factor equal to 3.0*3.0 = 9.0
The mutual force between them will be changed by factor of 9.0
Since in the case when he size of the charge value is tripled for both of two point charges maintained at a constant separation
So, the factor is
= 3(3)
= 9.0
In the case when the separation between the charges remains the similar, so the new value of the force will be directly proportional to the product of the charges.
