Explanation 1) Concept: We use the concept of magnetic force, centripetal force , and period. Using the magnetic force, we find the speed of the particle. From the centripetal force, we can find the radius of the circle. Using the equation of period for circular motion, we find the period of motion. 2) Formulae: i) F = q v B ii) F = m v 2 r iii) T = 2 π r v 3) Given: i) Magnetic field is B = 4.00 m T . ii) Magnetic force is F B = 3.20 × 10 - 15 N . iii) Figure 28-36 is the particle in magnetic field. 4) Calculations: The particle is moving counterclockwise. From the right hand rule, we determine that the particle is an electron. a) Speed of the particle: We use the equation of magnetic force to find the speed of the particle. F = q v B Plugging the values, we get 3.20 × 10 - 15 = ( 1.602 × 10 - 19 ) v ( 4.00 × 10 - 3 ) v = 3.20 × 10 - 15 1.602 × 10 - 19 4.00 × 10 - 3 v = 0.499 × 10 7 v = 4

Imagine you are out for a stroll on a sunny day when you encounter a lake. Unpolarized light from the sun is reflected off the lake into your eyes. However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.
