1. A laser produces a beam of light with a circular cross-section with a radius of 2.0 mm. If the peak electric field (the electric field amplitude) in the beam is 2300 V/m, then what is the total power delivered by the laser?

2.  In a series RLC circuit, suppose R = 300 W, L = 60 mH, C = 0.50 µF, and source voltage is Vs = (15 V)cos(20000?t). Find (a) voltage amplitudes across R, L, and C respectively, (b) the current expression which is a function of time t.
