Question

Q15.magnitude of the resultant vector is equal to the sum of magnitude of 2 vectors and its direction

is same as that of 2 given vectors

a) The 2 vectors act at some angle

b) The 2 vectors act in opposite direction

c) The 2 vectors are acting in same direction

d) The two vectors are mutually perpendicular to each other​

Answer 1

Answer:

d..............

Explanation:

d...........

Answer 2

Answer:

The correct option is C. The 2 vectors are in the same direction.

Explanation:

• An item with both magnitude and direction is referred to be a vector.
• A vector can be visualised geometrically as a directed line segment, with an arrow pointing in the direction and a length equal to the magnitude of the vector.
• The vector points in a direction from its tail to its head.
• The magnitude of the resultant of both vectors is the same as the sum of the magnitude of the 2 vectors
• This is possible only when both the vectors are in the same direction
• Since the vectors are in the same direction, they can be added algebraically and do not have to undergo vector addition.
• The resultant will also have the same direction as the 2 individual vectors

The 2 vectors are in the same direction.
