<span>The four main stages of the sun's predicted evolution in order from beginning to end are as follows:
main sequence (when a star's core is fusing hydrogen);
red giant (larger star, where no hydrogen remains in the core);
planetary nebula (surrounds an aging star; ring shaped nebula made of gas); and
white dwarf (smaller star that tends to be as large as an actual planet; after nebula state).</span>
You are almost there, often you are given a mass. But, here you already have a force. You just need to use:<span>W=Fd</span>Where W is work done, F is force, d is distance. Units of work will be Nm
Take the radius of the Earth 6 370 km.Then:
The semimajor axis:a = 6 370 + 360 = 6 730 km
Semiminor axis:b = 6 370 + 180 = 6 550 km
Eccentricity:ε = √ (a2+b2) / a = √ (6 7302+65502) / 6 730 ≈ 1.4
On axis of the dipole the electric field is given by
now if we approximate above equation
now we will find the ratio of these two
put r = 3d
<em>so above is the ratio of two field</em>
