Question # 1

Explain rectangular coordinates system.

  • Ans 1: Two lines drawn at right angles to each other are know as coordinate axes and their point of intersection is known as origin. This system of coordinate axes is called rectangular coordinate system.
    The horizontal line is named x-axis and vertical line y-axis.The direction of x-axis is positive towards right and y-axis is positive upward.

Question # 1

Two vectors have unequal magnitude. Can their sum be zero? Explain.

  • Ans 1: No, the sum of two vectors having unequal magnitudes can't be zero. The sum of two vectors will be zero only when their magnitudes are equal and they act in opposite direction.

Question # 1

The gravitational Force acting on a satellite is always directed towards the centre of the earth?

  • Ans 1: We known that the torque depends upon the moments arm and applied force. Mathematically we have
    T = r*F
    As we have given that the gravitational force acting on a satellite is directed towards the centre of the earth. As for central force, the moment arm is zero r= 0 so T = o*F = 0
    T= 0
    Eq (2) shows that the torque produced by gravitational force acting on a satellite zero

Question # 1

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

  • 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
