Two species of singly charged positive ions of masses 9.9×10⁻²⁷ kg and 2.7×10⁻²⁶ kg enter a magnetic field at the same location with a speed of 71000 m/s. the charge on the ion is 1.60218× 10⁻¹⁹ c. if the strength of the field is 0.1 t, and they move perpendicularly to the field, find their distance of separation after they complete one half of their circular path. answer in units of cm.

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?
