a parallelogramis constructed on the vectorsif `veca=3vecp+vecq` and `vecb=vecp-3vecq` angle between the `vecp & vecq`is `60^@ , a,b` are side of the parallogram then length of the diagonals : `|vecp|=2 &|vecq|=2`

If |vecP + vecQ| = |vecP -vecQ| the angle between vecP and vecQ is

If |vecP + vecQ| = |vecP -vecQ| the angle between vecP and vecQ is

Consider a parallelogram constructed on the vectors vecA=5vecp+2vecq and vecB=vecp-3vecq . If |vecp|=2, |vecq|=5 , the angle between vecp and vecq is (pi)/(3) and the length of the smallest diagonal of the parallelogram is k units, then the value of k^(2) is equal to

Consider a parallelogram constructed on the vectors vecA=5vecp+2vecq and vecB=vecp-3vecq . If |vecp|=2, |vecq|=5 , the angle between vecp and vecq is (pi)/(3) and the length of the smallest diagonal of the parallelogram is k units, then the value of k^(2) is equal to

If vecP*vecQ=0 , then angle between vecP and vecQ is 0^@ .

If vecP . vecQ =IvecP X vecQI the angle between vecP and vecQ is.

If vecP.vecQ=PQ then angle between vecP and vecQ is

If vecP.vecQ=PQ then angle between vecP and vecQ is

If vecP.vecQ=PQ then angle between vecP and vecQ is

if |vecP + vecQ| = |vecP| + |vecQ| , the angle between the vectors vecP and vecQ is
