The two vectors are orthogonal, if

What is the condition for two vectors are orthogonal ?

When do we say two vectors are orthogonal?

The dot product of two vectors vanishes when vectors are orthogonal and has maximum value when vectors are parallel to each other. Explain.

If veca,vecb and vecc are three vectors such that |veca|= 3, |vecb|=4 and |vecc|=sqrt(24) and sum of any two vectors is orthogonal to the third vector , then find |veca+vecb+vecc|.

If veca,vecb and vecc are three vectors such that |veca|= 3, |vecb|=4 and |vecc|=sqrt(24) and sum of any two vectors is orthogonal to the third vector , then find |veca+vecb+vecc| is equal to k.Find k .

If bar(a),b&bar(c) are three vectors such that, |bar(a)|=3,|bar(b)|=4&|bar(c)|=sqrt(24) and sum of any two vectors is orthogonal to the third vector, then |bar(a)+bar(b)+bar(c)| is equal to
