For Gauss’s law mark the correct statements . (1) If we displace the enclosed charges (within a Gaussian surface) without crossing the boundary, then both E→ and ϕ remain same. (2) If we displace the enclosed charges without crossing the boundary, then E→ changes but ϕ remains the same. (3) If the charge crosses the boundary, then both E→ and ϕ would change. (4) If we charge the boundary, then ϕ changes but E remians the same.
