Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

if a is constant vector , then answer is 0
Deepak sir, do you mean "a" has the same magnitude be it in 1,2, or 3-D space?
example of constant vector - 2i^ +3j^ + 4k^ or 4j^ etc. no need of magnitude
okay.
now tell Deepak sir.
I have also told same thing , a=(a1,a2,a3)=(2,3,4)= 2i^+3j^+4k^
2,3,4 are scalar
Thank you, Deepak sir.
welcome .. keep asking ..
