It is found that `|A+B|=|A|`,This necessarily implies.

It is found that |vecA+vecB|=|vecA| .This necessarily implies:

State true or false: If |veca|=|vecb| , then necessarily it implies veca=+-vecb .

In case of each of the following statements, state whether it is true or false : If |vec a|= |vec b| then necessarily it implies that |vec a|= pm |vec b|

If |bar(a)|=|bar(b)| , then necessarily it implies bar(a)=+-bar(b) .

If |veca|=|vecb| , then necessarily it implies veca=+-vecb .
