Answer:
It will decrease to one-sixth the original force.
Explanation:
The electrical force is given by :
[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]..............(1)
Where
k is the electrostatic constant
r is the distance between charges
One charge is decreased to one-third of its original value, and a second charge is decreased to one-half of its original value.
i.e. [tex]q_1'=\dfrac{q_1}{3}[/tex]
and [tex]q_2'=\dfrac{q_2}{2}[/tex]
New force is given by :
[tex]F'=k\dfrac{q_1q_2}{6r^2}[/tex]
[tex]F'=\dfrac{F}{6}[/tex]
So, the new force will decrease to one-sixth the original force. Hence, the correct option is (c).
