What are the conditions for two vectors to add to zero?
If the sum of two vectors is zero, then the magnitudes are equal, but the vectors point in the opposite direction.
What does it mean if the sum of two vectors is 0?
If the sum of two vectors is zero, then the magnitudes are equal, but the vectors point in the opposite direction.
What do you mean by polar vector?
In physics, a polar vector is a vector such as the radius vector that reverses sign when the coordinate axes are reversed. Polar vectors are the type of vector usually simply known as “vectors.” In contrast, pseudovectors (also called axial vectors) do not reverse sign when the coordinate axes are reversed.
What are the magnitude and direction of two vectors when their resultant is zero?
This means that when the sum of the 3 vectors is zero, “the resultant of any two has a magnitude equal to the magnitude of the third one, and a direction opposite to direction of that third one.”
Under what condition is the resultant vector equal to zero?
In case of three vectors, If three vectors acting on a point object at the same time are represented in magnitude and direction by the three sides of a triangle taken in the same order,their resultant is zero.
Which of the following vectors can give zero resultant?
(i) When three vectors are not lying in one plance, they can bot produce zero resultant. (ii) When three vectors are lying in a place and are represented in magnitude and direction by the three sides of a triangle taken in the same order, they can prokuce zero resultant.
What is unit vector magnitude?
Unit vectors are vectors whose magnitude is exactly 1 unit.
What is the magnitude of a unit vector Mcq?
Explanation: The magnitude of a unit vector is unity. It just gives the direction of a vector. A unit vector has no units or dimensions. 6.
