Question

Please help! Will rate lifesaver!

Part A) A 50mW laser produces a polarized beam of 600nm light. Ifthis laser light reflected normally off a perfect mirror, then whatis the net force of the radiation on the mirror?

I calculated the net force to be 3.33*10^-10 N.

Part B) At t=0 an 80 F capacitor is given a charge of200C and is connected across a 50mH inductor. What is theearliest time when the current is its maximum value (just themagnitude) and what is the maximum value?

Part C) A 2m long conducting rod is held at one end and rotated ina plane perpendicular to a constant magnetic field of 8mT. Ifit makes one complete rotation every 3s then what is the voltagedifference between the inside and outside?

Part D) After how many time constants has a discharging capacitorlost 95% of its charge?
