1how can we simply add the vectors??
is there nothin g like resultant
Find the ratio of the minimum and maximum of the resultant that can be found by two vectors of magnitude 4 and 6

1In this question
R =√a^2+b^2+2abcos theta
max value is when cos theta =1
and min when cos theta =--1
then it comes √1/9 = 1/3 =2/6
am i right or not???!!!!!!
1answer accord. to me is 1/5 ;
do the following vectors give maximum when in same direction
R1= 4+6 = 10
and minimum when in opposite direction
R2= 6-4=2
ratio = 2/10 = 1/5
1anirudh oyur ans as per tiit is right but i still cant understand the funda behind it
1when you say that angle between two vectors is zero what does it means that they are parallel and point in the same direction.
we can add these parallel vectors just like scalar by adding their signs.
that is what i have done. same answer would be reached by applying the formula.
