Answer:
2.00m
Explanation:
All we need to do to find the wavelength of the first intereference maximum is subtract both values we are given.
8.00 - 6.00 = 2.00m
Best of Luck!

Answer:
29.4 uN
Explanation:
The electric force between two charges can be calculated using Coulomb's Law. According to this law the force between two point charges is given as:
where k is a proportionality constant known as the Coulomb's law constant. Its value is Nm²/C²
r = distance between charges = 70 cm = 0.7 m
q1 = q2 = 4nC = C
The negative sign indicates that the charges are negative. In the formula we will only use the magnitude of the charges.
Using these values in the formula, we get:
Therefore, the magnitude of repulsive force between the given charges will be 29.4 uN
