    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

    Discuss the condition of equilibrium?

    • Ans 1: There are two condition of equilibrium which are given below.First Condition of equilibrium:According to the first condition of equilibrium, a body is said to be in equilibrium, if the vector sum of all external forces acting on the body is zero they cancel the effect of each other { F = 0In the component form we haveF1y+ F2y + F3y +................ +Fny =0Fy = 0A book lying on the table and paratrooper moving down words with uniform Velocity satisfies the first condition of equilibrium.Second Condition of Equilibrium:According to the condition of equilibrium, a body is said to be in equilibrium on a body is equal to zero.{ T = 0Explanation:There are certain situation in which on extended body will not be in equilibrium even when the first condition of equilibrium is satisfied. For Example, in the two equal forces are acting on a meter rod in opposite direction. As the line of action of these forces are not the same so the meter rod do not remain in state equilibrium and begins to rotate in anti clock wise direction. So the first condition of equilibrium is not sufficient in such a case Under such situations we should arrange the forces on the body in such a way, htat they causes clock-wise torque and anti-clock wise torque acting on the body simultaneously and cancel the effect other.

    Question # 1

    Can you add zero to a null vector?

    • Ans 1: No, zero can't be added to a null vector because zero is a scalar and scalars can't be added to vectors Only the physical quantities of same nature can be added.

    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.
