Let G be a connected graph and let e be a cut edge in G. Let K be the subgraph of G defined by:
V(K) = V(G) and
E(K) = E(G) - {e}
Prove that K has exactly two connected components. First prove that e cannot be a loop. Thus the endpoint set of e is of the form {v,w}, where v ≠ w. If ṽ∈V(K), prove that either there is a path in K from v to ṽ, or there is a path in K from w to ṽ
Here in the given the graph if we delete the edge which is loop(as like e7) then your graph G can't divide into 2 components
but this edge is not loop then graph G divide into 2 components in which there exits a path.
