State with reasons, whether the following algebraic operations with scalar and vector physical quantities are meaningful:.

The addition of two scalar quantities will be meaningful only if they both represent the same physical quantity. The addition of a vector quantity with a scalar quantity is considered not meaningful. A scalar can be multiplied with a vector. Force is multiplied with time to give impulse. A scalar, respective of the physical quantity, can be multiplied with another scalar having the same or different dimensions.

The addition of two vector quantities is considered meaningful only if they both represent the same physical quantity. A component of a vector can be added to the same vector as both of them have the same dimensions. Read each statement below carefully and state with reasons, if it is true or false:. The magnitude of a vector is a number. So, it is a scalar. Each component of a vector is a vector. The total path length is scalar, whereas displacement is a vector quantity.

So, the total path length is greater than the magnitude of displacement. It is equal to the magnitude of displacement only when a particle is moving in a straight line. It is because the total path length is always greater than or equal to the magnitude of displacement of a particle.

Establish the following vector inequalities geometrically or otherwise:. When does the equality sign above apply? Image will be uploaded soon. As each side is smaller than the sum of the other two sides in a triangle,. If the two vectors act in a straight line but in opposite directions, then:. The L. S is always positive and R. S can be positive or negative. To make both quantities positive, take modulus on both sides. If the two vectors act in a straight line but in the same direction:.

There are many other combinations which will give the sum zero. Take modulus on both sides:. This is true in this case and the vector sum of all the vectors will be zero. What is the magnitude of the displacement vector for each? For which girl is this equal to the actual length of the path skated? The magnitudes of displacements are equal to the diameter of the ground. Ans So, his net displacement is zero.

As the net displacement of the cyclist is zero, his average velocity is also zero. Starting from a given turn, specify the displacement of the total at the third, sixth and eighth turn. Compare the magnitude of the displacement with the total path length covered by the motorist in each case. Magnitude of displacement. Total path length.
