Detailed explanation-1: -So, since both the vectors are in the same direction, the angle between them will be theta equal to 0 degree. So the resultant magnitude of vector a square and magnitude is 10 meters, so we will be square 10 meter and the magnitude of vector b is also same 10 meters.
Detailed explanation-2: -Two vectors acting in the opposite directions have a resultant of 10 units. If they act at right angles to each other, then the resultant is 50 units.
Detailed explanation-3: -Two vectors, both equal in magnitude, have their resultant equal in magnitude to any of the two vectors.
Detailed explanation-4: -R = A + B. Formula 2 Vectors in the opposite direction are subtracted from each other to obtain the resultant vector. Here the vector B is opposite in direction to the vector A, and R is the resultant vector.
