Question

what is common between charge and mass does mass changes with velocity or charge varies with velocity​

Answer 1

mass changes ith velocity

Answer 2

Both require particles of some kind in order to manifest. Charge is carried by things such as protons and electrons; mass is an aspect of matter (and energy, its other form), which is particulate.

Both are quantized. Charge comes in discrete amounts (such as ±1/3 or ±2/3 for quarks, or ±1 for electrons and protons); mass has similar chunks (such as the electron mass, the up quark mass, etc.).

Both respond to forces that have an inverse-square nature with respect to distance
