Question: Show by explicit calculation that the formulae for the charge and current densities of a collection of point charges, have exactly the same form when

Show by explicit calculation that the formulae for the charge and current densities of a collection of point charges,

N N p(r, t) = [qkd(r - rz(t)) and j(r, t) =

have exactly the same form when we boost from frame K to frame K' by a velocity v0.


Show first that9k Vk(t) 8(r - rk (t)), k=1 k=1by evaluating the Jacobian determinant in the volume element transformationimage

N N p(r, t) = [qkd(r - rz(t)) and j(r, t) = 9k Vk(t) 8(r - rk (t)), k=1 k=1
