ntProblemID 91466350 Hico Tiner: 00:36:05 00:36:05 Quiz_01 onceptual Question 1.18 ) 40f 10 (> Part A If the eastward component of vector A is equal to the westward component of vector B and their northward components are equal. Which one of the following statements about these two vectors is correct? O Vector A is perpendicular to vector B O The magnitude of vector A is equal to the magnitude of vector B O Vectors A and B point in opposite directions. O The magnitude of vector A is twice the magnitude of vector B. Vector A is parallel to vector B Request Answer

Explanation / Answer

Correct option is :- The Magnitude of vector A is equal to the magnitude of vector B.

Explaination:-

Ax = - Bx ( both are equal and B is -ve as it is in westward direction, both along x axis )

Ay = By (along y axis)

therefore,

| A | = Ax2 + Ay2 = Bx2  + By2 = | B | ( magnitude formula / Squaring cancels the negative sign of B )
