## Homework Statement

In laboratory's frame the angle between vectors

**E**and

**H**is given φ. Find the frame where these vectors will be parallel.

## Homework Equations

## The Attempt at a Solution

I suppose I should require equal angle between each of the

**E'**and

**H'**and axes in the ''new'' frame.

Means this: E'

_{||}/|

**E**'|=H'

_{||}/|

**H**'|

After this I lose the key. How can I implement the given angle φ?
