Question

the ratio of the magnitude of the resultant of the two vectors when they are perpendicular and when they are parallel is 1:5 the ratio of the resultant of the same two vectors when they are perpendicular and antiparallel is 3:1 . then the least integral magnitude of smaller of the two vector is ?​

Answer 1

Answer:

Explanation:

When two non-zero vectors and b are perpendicular to each other, When two forces of magnitude P and Q are perpendicular to each other, their resultant is of magnitude R. When they are at an angle of 180∘ to each other, their resultant is of magnitude R√2.
