A point charge q_1=-4.00\;{\rm nC} is at the pointx = 0.600 meters, y = 0.800 meters, and a second pointcharge q_2=+6.00\;{\rm nC} is at the pointx = 0.600 meters, y = 0.

A)Calculate the magnitude E of the net electric field at the origin due tothese two point charges.

B)What is the direction, relative to the negative x axis, of the net electric field at the origin due to these two pointcharges.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
