Thanks for the reply. I believe that that formula works both for rms values and peak values. This should give me the rms value of the electric field E = (3 x 108)(0.137 T) = 4.11 x 107 V/m If I convert the magnetic field rms value to peak I would get Brms x \sqrt{}2 = B[SUB]peak 0.137 T x...

Homework Statement Hi, here is the problem I'm having trouble with: The rms value of the magnitude of the magnetic field in an electromagnetic wave is Brms = 0.137 T. The intensity of this wave is approximately... Homework Equations E = cB I = (ErmsBrms) / \mu0 The Attempt at a...

Thanks, I was using the wrong angle. In the future, how should I go about choosing the correct angle?

Hi, thanks for the reply, I got sin\theta = 0.6, using the dimensions of the right triangle with the distance between Q1 and Q2 being 60nm and the distance between Q2 and P being 80nm, so the hypotenuse would be 100nm 602 + 802 = 1002. Then sin\theta = 60nm / 100nm. Is this wrong? Thanks

Homework Statement Hi, here is the problem I'm having trouble with: Three charges Q1, Q2, and Q3, each equal to 6.4 × 10–19 C, are in a straight line. The distance between neighboring charges is 60 nm. Find the magnitude of the electric field at P, which is 80 nm from Q2 on a line at right...

I think I got it now, thanks I appreciate it.

Homework Statement Here is the problem, I am able to calculate the velocity, but I don't know where to go from there. A legendary Dutch boy saved Holland by plugging a hole in a dike with his finger, which is 1.10 cm in diameter. (a) If the hole was 2.40 m below the surface of the North...

I got about 10.6m/s. Thanks I appreciate it. Is t used since it would have the same value in both the x and the y components?

Homework Statement I'm having trouble finding the initial velocity without knowing the time. A basketball player is standing on the floor 10.0 m from the basket. The height of the basket is H = 3.05 m, and he shoots the ball at an angle, θ = 42.0°, with the horizontal from a height of h =...
