So if you put that together, moving the test charge to twice its original distance, the charge enclosed by a spherical shell centered on the origin and just touching the test charge has increased by a factor of 8. Due to inverse square, the attraction induced by a given charge has decreased by a factor of 4.gracy said:4 times.
By what factor has the attraction of the test charge to the enclosed charge increased or decreased? Has it increased? Has it decreased?
