Question

A rocket zooms past the earth at $v=2.0\times 106m/s$. Scientists on the rocket have created the electric and mag-netic fields shown in FIGURE EX31.5. What are the fields measured by an earthbound scientist?

Short answer

The fields measured by an earthbound scientist are

$\stackrel{\rightharpoonup }{E_b}=-1.0\times {10}^6\hat{R}$

$\stackrel{\rightharpoonup }{B_b}=0.99\hat{j}T$

Step-by-step solution

Given Information

We are given that

velocity of rocket is $2.0\times {10}^{6}m/s$, magnetic field is $1.0T$and electric field is $10\times {10}^{6}V/m$

We need to find the fields measured by an earthbound scientist.

Simplify

As rocket is separating from earht the relative velocity of rocket with respect to earth i.e.

V$V_{ba}$
