Question # 1

What is the minimum number of unequal vector in to a null vector?Explain

  • Ans 1: The minimum number of unequal vector to result in to a null vector must be three. If we add three vector of unequal magnitude in such a way that they forms the sides of a triangle, then their resultant must be zero.
    In the given figure three vectors A, B, and C are added according to head to tail rule and they form the side of a triangle. Now for getting their resultant, we will combine the tail of A with the head of C which already coincides each other. Thus we get a null vector or zero vector as a resultant
    R= A+B+C = 0

Question # 1

DIscuss the addition of vectors by graphical Method or geometrical Method?

  • Ans 1: We can add two or more than two vectors by geometrical method or graphical method to get their resultant vector. we use "Head-to-Tail rule for addition of vectors by graphical method or geometrical method.
    The following steps must be followed to add vectors buy head-to-tail rule:
    1. Select a suitable scale for the representation of given vectors
    2. Draw the 1st vector according to the selected scale in the given direction
    3. Draw the second vector according to the selected scale in the specified direction such that its tail touches the head of the first vector.
    4. Now draw the 3rd vector according to the selected scale in the specified direction such that its tail touches the head of the second vector
    5. Continue the above process for given number of vectors.
    6. For getting the resultant vector, combination the tail of the first vector.
    7. Measure the length of R which will given its magnitude.
    8. To determine the direction of R measure the angle of R with respect to positive X-direction in anti clock wise sense.

Question # 1

Define position vector and resultant vector.

  • Ans 1: Position Vector: A vector which describes the location of a point with respect to origin is called position vector.

    Resultant Vector: A Single vector which would have the same effect as all the original vectors taken together.

Question # 1

How would the two vectors of the same magnitudes have to be oriented,if they were to be combined to give a vector of the same magnitude?

  • Ans 1: The two vectors of equal magnitudes are combined to give a resultant vector of same magnitude when must be oriented at an angle of 1200 With each other.
