Explanation Given data: The prism is an equilateral prism. The traversing ray is parallel to the bottom of the prism. The angle of incidence θ 1 = 40 ° Formula used: Consider the expression for Snell’s law. n 1 sin θ 1 = n 2 sin θ 2 Here, n 1 is the refractive index of first medium, n 2 is the refractive index of second medium, θ 1 is the angle of incidence, and θ 2 is the angle of refraction. Modify the equation to find n 2 . n 2 = n 1 ( sin θ 1 sin θ 2 ) (1) Explanation: From table 18.1, the refractive index of air is n 1 = 1 . Since the prism is an equilateral triangle, all the angles of the triangle are same that is 60 ° . Ray diagram of the prism is drawn as shown in Figure 1.

Four point charges of equal magnitude Q = 55 nC are placed on the corners of a rectangle of sides D1 = 27 cm and D2 = 11cm. The charges on the left side of the rectangle are positive while the charges on the right side of the rectangle are negative. Use a coordinate system where the positive y-direction is up and the positive x-direction is to the right. A. Which of the following represents a free-body diagram for the charge on the lower left hand corner of the rectangle? B.

Point charges q1=50.0μC and q2=-35μC are placed d1=1.0m apart, as shown. A. A third charge, q3=25μC, is positioned somewhere along the line that passes through the first two charges, and the net force on q3 is zero. Which statement best describes the position of this third charge?1) Charge q3 is to the right of charge q2. 2) Charge q3 is between charges q1 and q2. 3) Charge q3 is to the left of charge q1. B. What is the distance, in meters, between charges q1 and q3? (Your response to the previous step may be used to simplify your solution.)Give numeric value.d2 = __________________________________________mC. Select option that correctly describes the change in the net force on charge q3 if the magnitude of its charge is increased.1) The magnitude of the net force on charge q3 would still be zero. 2) The effect depends upon the numeric value of charge q3. 3) The net force on charge q3 would be towards q2. 4) The net force on charge q3 would be towards q1. D. Select option that…
