Let m = mass of earth
<span>let r = radius of earth </span>
<span>let a = acceleration due to gravity on earth </span>
<span>G = constant (it doesn't change) </span>
<span>If you plug in the mass and radius of the new planet, you get </span>
<span>a = G (.5m)/(2r)^2 </span>
<span>a = 1/8 (Gm/r^2) </span>
<span>so the acceleration on the new planet is 1/8 what it is here.</span>
The similarity between electric field and magnetic field is that both fields attract or repel charges in the field.
<h3>What is electric field?</h3>
An electric field is a region of space that surrounds electrically charged particles and exerts force on other charged particles within the filed.
<h3>What is magnetic field?</h3>
A magnetic field is a vector field that describes the magnetic influence on moving electric charges.
<h3>Similarity between electric field and magnetic field</h3>
