Consider the electric field lines for two point charges separated by a small distance. what are the signs of q1 and q2?

Assume positive charges

directions outwards from source points like field lines of two repelling magnets

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
