1.	The vectors `vecA`and `vecB`are such that`\|vecA+vecB\|=\|vecA-vecB\|`The angle between the two vectors is:-A. `90^(@)`B. `60^(@)`C. `75^(@)`D. `45^(@)`
Answer» Correct Answer - A `\|vecA+vecB\|=\|vecA-vecB\|implies\|vecA+vecB\|^(2)=\|vecA-vecB\|^(2)` ` impliesA^(2)+B^(2)+2AB cos0=A^(2)+B^(2)-2AB cos0` `impliescos 0=0implies0=90^(@)`
