Question

is the converse necessarily true that electric field is zero everywhere then charge contained must be zero?​

Answer 1

Answer:

When the total charge enclosed by a surface is zero,it does not imply that electric field everywhere on the surface is zero, As ∮→E. →ds=q∈0=0. Therefore, the field may be normal to the surface. The converse is, however true, i.e, when E=0 everyone on a surface, net charge inside is zero.

this is the answer
