Question

The resultant of two vectors is R when vector A is reversed and again added to vector B the resultant turns through 90.find the relation between vector A and vector B

Answer 1

If two vectors of equal magnitude have a resultant equal to either of them then what will be the angle between them? Let A be the magnitude eof each of the equal vector. ... If the resultant is equal to half the magnitude of two equal forces, then what is the angle between the forces

Answer 2

Hey dear,

● Answer -
Vector A & vector B are parallel vectors.

● Explanation -
Resultant of two vectors is given by formula -
tanθ = A/B ...(1)

When A is reversed, resultant of two vectors is -
tan(θ+90) = -A/B ...(2)

Solving (1) & (2),
Angle between A & B is 0° making them parallel vectors.


Hope this helps you...
