Question

a 35N force makes an angle of 140 with x axis Determine its components along the lines making angy of 300 and 240 with x axis.. please give proper explaination​

Answer 1

Answer:

5N

Explanation:

Given:

A force of 10N makes an angle of 30° with y-axis. Find the magnitude of x-component?

Solution:

Since this force does make an angle of 30[math]^\circ[/math] with the y-axis we now have a 30[math]^\circ[/math] - 60[math]^\circ -9[/math]0[math]^\circ[/math] right triangle.

To find the x magnitude we take the sin of 30[math]^\circ[/math] [math]\times[/math] the force of 10N (hyp.) or sin 30[math]^\circ[/math] = x/10N ===> x = 10N[math]\cdot[/math]sin30[math]^\circ[/math] ===> x = 5 N

Answer is: 5N
