Two parallel metal plates, each of area A, are separatedby a distance 3d. Both are connected to ground and each plate carries no
charge. A third plate carrying charge Qis inserted between the two plates, located a distance dfrom the upper plate. As a result, negative charge is induced on each of the two original plates. a) In terms of Q, find the amount of charge on the upper plate, Q1, and the lower plate, Q2. (Hint: it must be true that Q

Answer:
r = 29.53 degrees
Explanation:
Given that,
Angle of incidence,
We need to find the angle at which it will travel in the water. The refractive index of water is 1.33 and refractive index of air is 1. Using Snell's law as :
r is the angle of refraction
So, the ray will travel at an angle of 29.53 degrees in the water.
