[QUOTE="rude man, post: 5081110, member: 350494"] I'm a bit mystified by your answer to (b) and (c). [B]E[/B] is a vector with y and z components, so is [B]B. [/B] Neither has an x component. I don't see an expression for the vector fields of [B]E[/B] or [B]B[/B] that I can understand. Depending on the direction of rotation of the E-B plane, you need to come up with something like [B]E[/B] = E[SUB]y[/SUB][B] j[/B] + E[SUB]z[/SUB] [B]k B[/B] = B[SUB]y[/SUB] [B]j[/B] - B[SUB]z[/SUB] [B]k[/B] including an expression showing the dependency of the [B]E[/B] and [B]B[/B] vectors with x and t. where[B] j[/B] and [B]k[/B] are unit vectors in the y and z direction resp. (Don't confuse k with [B]k).[/B] Note the + and - signs above. They get reversed if the rotation is in the other direction. [/QUOTE]
