I was trying to solve this one, but couldn't come up with any way to start.
In 1959 Lyttleton and Bondi suggested that the expansion of the Universe could be explained if matter carried a net charge. Suppose that the Universe is made up of hydrogen atoms with a number density N, which is maintained a constant. Let the charge on the proton be: ep = – (1 + y)e where e is the electronic charge.
(a)Find the critical value of y such that expansion may start.
(b)Show that the velocity of expansion is proportional to the distance from the centre.
Attempt at solution-
since charge assumed on proton is -(1+y)e, there is net charge in atom. also the force is repulsive, not attractvie. I started with taking a spherical gaussian surface and thts it! i couldn't go any further.
