Answer:
9.05 W
Explanation:
The given formula is
where r is in centimeters and P is in Watts
Making Power, P the subject from the above formula

Substituting r with 12 cm then

Answer:
D) ¼ as large
Explanation:
The magnitude of the electric force between two charges is

where
k is the Coulomb's constant
q1 and q2 are the magnitudes of the two charges
r is the separation between them
From the formula we see that the magnitude of the force is inversely proportional to the square of the distance.
In this problem, the distance is doubled:

So the new force will be

So the force will decrease to 1/4 of its original value.
