Similarities between Gravity and Electromagnetism
I recently noticed some striking similarities between gravity and electromagnetism .
Like both work on the principle of fields .
We can use the Equations of finding electric field in different regions of non conducting sphere ( inside , outside , on ) and apply it to find gravitational fields for spherical body .
( I have very little knowledge of General theory , I refer here to classical mechanics )
There are many more such similarities .
So extending this further :- as there exists positive and negative charge , can a body with negative mass exist ???
Thank you in Advance (:
