OUIZ Chapter 3 Q.1.Is it possible to add a vector quantity to a scalar quantity? Explain. Q.2. The cartesian coordinates of a point in the xy plane are (x,y) - (-3.50,-2.50)m as shown in figure. Find polar coordinates of this point. y (m) Q.3 Consider the two vectors, A 3i 2j and B 4j. Calculat (a) A B, (b) A B (IA BI. d IA,B. and (e) the directions of A + B and A B Q.4 Consider the three displacement vectors A (si 3j) m, B (i 4j) m, and (-2i + 5j) m. Use the component method to determine (a) the magnitude and direction of D A+B+C and (b) the magnitude and direction of E -A B + C Q-5 Vector A has x and y components of -8.70 cm and 15.0 cm, respectively; vector B has x and y com- ponents of 13.2 cm and -6.60 cm, respectively f A-B + 3 C (), what are the components of C ?

Explanation / Answer

1) No, it is not possible to add a vector quantity to a scalar quantity. The reason is that they have different dimensions in space so it is impossible to add vector to a scalar.
