Explanation Given data: Deflection angle of the horizontal laser beam is 60 ° . Formula used: Write the expression for law of reflection. θ r = θ i (1) Here, θ i is the angle of incidence. θ r is the angle of reflection. Explanation: Draw the ray model of light as shown in Figure 1. Write the expression for θ i from Figure 1. θ i = 90 ° − ϕ Write the expression for θ r from Figure 1. θ r = 90 ° − ( 60 ° − ϕ ) Substitute (

When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture? B
