What will the surface charge density be if the radius of the disk is doubledA circular disk has surface charge density 30 nCcm2.?

The surface charge density will remain constant at 30 nC/cm^2 even if the radius of the disk is doubled. Surface charge density is independent of the size of the object and depends only on the distribution of charge over its surface area.
