प्रश्न

Suppose a is a vector of magnitude 4.5 units due north. What is the vector (a) 3a, (b) 4a ?

संक्षेप में उत्तर

उत्तर

Given: a is a vector of magnitude 4.5 units due north.

Case (a):
3|a|=3×4.5=13.5

3a is a vector of magnitude 13.5 units due north.

Case (b):
|4a|=4×4.5=18 units 

4a is a vector of magnitude 18 units due south.
