When can we say that the resultant of the two vectors is maximumWhen the vectors are acting in the opposite directionBoth the vectors are acting in the same directionWhen the vectors are at right anglesWhen the vectors are parallel to each other​

Answer»

Answer:

. R is maximum when Cos ( A, B) = +1 ie ANGLE between vectors A and B is ZERO ie vectors A and B are parallel to each other. The RESULTANT of two VECTOR is minimum when both vectors are equal and in opposite direction i.e. the angle between the vector is 180 degrees.
