The angle can have any value.
vector equal in magnitude and opposite direction
69 degrees
2pi/3 radian or equivalent 120 degree
If the angle decreases, the magnitude of the resultant vector increases.
If the sum of the squares of the vector's components is ' 1 ',then the vector's magnitude is ' 1 '.
vector equal in magnitude and opposite direction
69 degrees
2pi/3 radian or equivalent 120 degree
iff the angle between them is 120 degrees
If the angle decreases, the magnitude of the resultant vector increases.
If the sum of the squares of the vector's components is ' 1 ',then the vector's magnitude is ' 1 '.
Sum of two vectors can only be zero if they are equal in magnitude and opposite in direction. So no two vector of unequal magnitude cannot be added to give null vector. Three vectors of equal magnitude and making an angle 120 degrees with each other gives a zero resultant.
If the directions of two vectors with equal magnitudes differ by 120 degrees, then the magnitude of their sum is equal to the magnitude of either vector.
Depends on the situation. Vector A x Vector B= 0 when the sine of the angle between them is 0 Vector A . Vector B= 0 when the cosine of the angle between them is 0 Vector A + Vector B= 0 when Vectors A and B have equal magnitude but opposite direction.
The magnitude of the vector sum will only equal the magnitude of algebraic sum, when the vectors are pointing in the same direction.
Distance traveled is equal to the magnitude of the displacement vector when the motion is in a straight line.
No, by definiton, a unit vector is a vector with a magnitude equal to unity.
