Question

8)The component of a vector is
a) always less than its magnitude b) always greater than its magnitude
c) always equal to its magnitude d) none
---------------------------------------------------------------------
9)If a vector is along the horizontal direction, its vertical component is
a) maximum b) minimum c) zero
d) none
​

Answer 1

Answer:

8) d.

9) c.

Explanation:

for question 8 components can add up to or minus each other to make one vector, so it depends on the direction of the components.

for question 9 since the vector is moving horizontally, vertical components cancel each other because they are equal but in opposite directions.

Answer 2

Answer:

8:- (c) always equal to its magnitude
