In this question, force f1 is equal to 20 newton when theta is 25 degree.
00:09
And force f2 is 35 newton when theta is 120 degree.
00:16
The force along x -axis is f -cost theta, and the force along y -axis is f -sign theta.
00:24
This is known to us along theta its cost and perpendicular to its sine.
00:29
So force along 1, f1 along x will be 20 cores 25 degree.
00:38
Solving this we get 18 .126 newton.
00:43
Similarly, force f1 along y -axis will be 20 sine 25 degree.
00:50
Solving this we get 8 .452 newton.
00:55
Similarly, f2 along x axis will be equal to 35.
01:01
Cos 120 degree, that is minus 17 .5 newton.
01:08
Similarly, force along f2 along y -axis is equal to 35 sine 120, that is 30 .310 newton.
01:23
Finding the total force along x -axis, that will be f1x plus f2x...
