1) In classical electrodynamics, does a charged particle experience any force exerted by the electromagnetic field it creates itself?(adsbygoogle = window.adsbygoogle || []).push({});

2) In general relativity, does the world-line of a lonely point mass obey the spacetime curvature created by the stress energy tensor created by the point mass?

3) In general relativity, in a system of 2 point masses, does the world-line of point mass A obey the spacetime curvature created by the stress energy tensor created by A or does the world-line of point mass A obey the spacetime curvature created by the stress energy tensor created by both particle A and particle B?

4) In a gas of N particles of point masses, does all the world-lines of all the point masses obey the spacetime curvature created by the stress energy tensor created by the N point masses or N-1 point masses?
