One charge is decreased to one-third of its original value, and a second charge is decreased to one-half of its original value. how will the electrical force between the cahrges compare to the original force
it will decrease to 6 times the original force
it willnincrease to 36 times the original force
it will decrease to one-sixth the original force
it will decrease to one-thirty-sixth the original force

The new force will decrease to one sixth the original value.

Explanation:

It is given that,

One charge is decreased to one-third of its original value, and a second charge is decreased to one-half of its original value.

Let, q₁ is the charge 1

q₂ is the charge 2

Initially, the electrical force between the charges is given by :

...........(1)

Let F' is the new force i.e.

So,

 (from equation 1)

Hence, the new force will decrease to one sixth the original value.

this means that the temperature of both substances will be equal
