sir please tell me that if we have to find the difference like difference in velocity etc (any vector quantity ) should we find it by taking magnitude of vector quantities or we must consider their components ???
Dear Ankit shukla if you are asked to find the difference in velocity.then you need to find the difference in velocity vector not the difference of there magnitude inless untill it is mention to find the difference in their magnitude Example : V1 =2i +3j+4k V2 =4i+5j+ 5k then difference is V2-V1 =2i +2j+k Please feel free to post as many doubts on our discussion forum as you can. If you find any question Difficult to understand - post it here and we will get you the answer and detailed solution very quickly.

Dear Ankit shukla
if you are asked to find the difference in velocity.then you need to find the difference in velocity vector
not the difference of there magnitude inless untill it is mention to find the difference in their magnitude
Example :
V1 =2i +3j+4k
V2 =4i+5j+ 5k
then difference is V2-V1 =2i +2j+k
