Angular Acceleration due to Light Waves

[QUOTE="JackFlash, post: 3595379, member: 368559"] I found the correct answer (1.46x10[SUP]-13[/SUP]) after a bit of trouble (I was calculating Intensity wrong, haha...). I'm going to post a quick run through of my work so that anyone who invariably stumbles upon this problem might see it worked out neatly. Intensity = E[SUB]max[/SUB][SUP]2[/SUP]/2μ[SUB]o[/SUB]c = .001754 P[SUB]rad[/SUB] total is Intensity/c on the silvery square. P[SUB]rad[/SUB] = F/Area F = (Intensity)(Area)/c Torque τ = Fd = α(Inertia). (Inertia) = md[SUP]2[/SUP] + md[SUP]2[/SUP] (for both cubes on the weightless rod) Values: d = 1/2m, m = .004kg (force acts on one square), Area = 1x10[SUP]-4[/SUP] (Inertia) = m/2 Bring it all together with some fancy substitutions: α = 2(Intensity)(Area)/2cm = ANS. Many thanks for the help. If I ever encounter you in real life, I shall give you a burrito. [/QUOTE]
