There are two displacement vectors , one of magnitude 3m and other of 4m . How should the two vecotrs be added so that the resultant vector be
7 m ,

Text Solution

Verified by Experts

As `R = sqrt(A^(2) + B^(2) + 2AB cos theta)`
For 7 m both the vectors should be parallel i.e., angle between them should be zero.
