In this question, two vectors are given and the vector a is 50 newton along 25 degree north of east and vector b which is 25 newton along east.
00:22
We need to find the resultant vector by using parallelogram, low of vector addition and polygon low of vector addition.
00:35
So consider the vectors.
00:40
So it can be represented as this is north, this is south, this is east and this is west.
00:52
So this is the vector a, that is having 50 newton along the direction 25 degree north of east.
01:07
And the vector b, which is 20.
01:14
25 newton along the east direction.
01:21
So by using the low effect tradition we can draw a vector having same magnitude as of b here.
01:34
So this is also vector b.
01:37
Also we can draw a similar vector a here.
01:49
So considering these two vectors.
01:53
This is vector a, this is vector a.
01:54
This is a vector b the sum or the resultant vector will be the diagonal so this will be vector a plus vector b that is in case of parallelogram low effector addition diagonal of the parallel represents the result and vector that is a plus b then we need to solve the result and vector using the polygon method considering the diagram this is north south east and west so this is the vector a and it is having magnitude 50 newton along the 25 degree north of east and we need to draw another diagram like this the representation of north, south, east and west.
03:20
So considering this point the vector b is along the east direction with a magnitude 25 newton.
03:34
So this is vector a and this is vector b...
