Answer:
The magnitude of each charge is
Explanation:
Suppose the two point charges are separated by 6 cm. The attractive force between them is 20 N.
We need to calculate the magnitude of each charge
Using formula of force
Where, q = charge
r = separation
Put the value into the formula
Hence, The magnitude of each charge is
Answer:
the question seems incomplete but the most reasonable answer is 4 times
