Question

Match List I with List II from the combinations shown.
List - I
a)Addition of vectors
b)dot product
c) cross product
d) subtraction of Vectors
List - II
e)relative velocity
f)resultant velocity
g)work done
h) torque vectors
The correct match is

• A. $a\to e;b\to f;c\to g;d\to h$
• B. $a\to h;b\to g;c\to f;d\to e$
• C. $a\to f;b\to g;c\to h;d\to e$
• D. $a\to g;b\to h;c\to e;d\to f$

Answer 1

Answer: (C)

$a\to f;b\to g;c\to h;d\to e$

Addition of vectors gives resultant of two vectors. ( so correct match is resultant velocity)
Dot product of vectors gives a scalar quantity. (so correct match is work done)
Cross product of vectors gives an angular vector. (so correct match is torque vector)
Subtraction of vectors gives relative value vectors. (so correct match is relative velocity)
