Suppose we now rotate the last polarizer by 90 degrees so that its transmission axis becomes aligned with the x-axis. With the beam still incident from the right (on the polarizer whose transmission axis makes an angle θ2 with the x-axis), what is the Ifinal, RLnew, the intensity of the beam immediately following the last polarizer (transmission axis aligned with the x-axis)?

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.
