Derive the formula for the electric field e to accelerate the charged particle to a fraction f of the speed of light c. express e in terms of m, q, d, f, c and v0. – (a) using the coulomb force and kinematic equations. (8 points) – (b) using the work-kinetic energy theorem. ( 8 points) – (c) using the formula above, evaluate the strength of the electric field e to accelerate an electron from 0.1% of the speed of light to 90% of the speed of light. you need to look up the relevant constants, such as mass of the electron, charge of the electron and the speed of light. (5 points)

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
