Can two vectors, of unequal magnitude, add up to give the zero vector? Can three unequal vectors? Under what conditions?
Step 1 of 1
The vector sum of the two vectors with unequal magnitudes can not be zero. However, the vector sum of the two vectors will be zero when both the vectors have equal magnitude and are acting in opposite direction.
Three unequal vectors can add up to give a zero vector under a specific condition. If the vector sum of any two vectors is equal in magnitude and opposite in direction to the third vector, the sum of the three unequal vectors will be zero.
