Question

Someone please help with this

Answer 1

The new force is 2/3 of the original force

Step-by-step explanation:

Coulomb's Law

The electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.

Written as a formula:

`\displaystyle F=k(q_1q_2)/(d^2)`

Where:

`k=9\cdot 10^9\ N.m^2/c^2`

q1, q2 = the objects' charge

d= The distance between the objects

Suppose the first charge is doubled (2q1) and the second charge is one-third of the original charge (q2/3). Now the force is:

`\displaystyle F'=k(2q_1*q_2/3)/(d^2)`

Factoring out 2/3:

`\displaystyle F'=(2)/(3)k(q_1*q_2)/(d^2)`

Substituting the original force:

`F'=(2)/(3)F`

The new force is 2/3 of the original force
