Question

two forces of magnitude 8N making an angle of 30 and 120 with xaxis . the y component of resultant                                    A/ O                                                B/ 4N                                               C/ 8N                                            D/ 16N

Damon · Answer

8 sin 30 + 8 sin (180-120) 4 + 8 (.866) = 4+6.93 = 11 N In other words none of the above I bet you mean 30 and 150 with x axis in which case C
