I have a problem that I can not understand what I am doing wrong.(adsbygoogle = window.adsbygoogle || []).push({});

A rocket moves at 1.0*18^6 m/s. Inside is an E Field (coming out of the page of the book) that is 2.0*10^6 V/m. There is also a B Field in the rocket pointing up that is -1.0 T. What is the E Field observed by someone on Earth. (The rocket is sooming past Earth.)

I used E = E - V X B

= E - V*B (V and B are perpindicular)

= sqrt((1.0*10^6)^2 + (2.0*10^6)^2)

However this does not yield the correct answer. Any help is appreciated.

If anyone is working the numbers I got 2.24*10^6.
