Here we have to solve the following problem.
00:03
Here we have to find the resultant vector and this resultant vector is a vector sum of all four vectors.
00:11
Now let's calculate the x component of this resultant vector.
00:31
So here a is 2 .5.
00:55
Now let's complete this calculation.
01:20
That is 11 .2 centimeters.
01:22
Now we have to do the same with the y component.
01:24
Y component is a sine of 70 plus d cosine 50 minus b sine 20 minus c cosine of 36 oh actually i guess i have to double check my calculation above because here c has to be multiplied by sign of 36 also that has to be 12 .5 centimeters and now let's let's complete the last part of this calculation.
02:22
So here, actually, we also have to add d.
02:27
Actually, we've already done it.
02:29
So now let's complete this calculation.
03:27
That is negative 1 .25 centimeters.
03:31
So it means that the magnitude of r is this sum...
