Question

The resultant of two vectors vec(P) and vec(Q) is vec(R ). If the magnitude of vec(Q) is doubled, the new resultant vector becomes perpendicular to vec(P). Then, the magnitude of vec(R ) is equal to

Answer 1

Answer:

The resultant of two vectors →P and →Q is →R. If the magnitude of →Q is doubled, the new resultant vector becomes perpendicular to →P. Then, the magnitude of →R is equal to.
