Answer:
Explanation:
In this case we have to work with vectors. Firs of all we have to compute the angles between x axis and the r vector (which points the charges):
the electric field has two components Ex and Ey. By considering the sign of the charges we obtain that:
Hence, by replacing E1 and E2 we obtain:
hope this helps!!
Answer:
0.737
Explanation:
= Refractive indices of liquid A
= Refractive indices of liquid B
= Refractive indices of liquid C
Consider the total internal reflection at interface of liquid A and liquid B
= Angle of incidence = 32.0
Using Snell's law for total internal reflection
Consider the total internal reflection at interface of liquid A and liquid C
= Angle of incidence = 46
Using Snell's law for total internal reflection
Ratio is hence given as
