Three boys are pulling a heavy trolled by means of three ropes. The boy in the middle is exerting a pull of `100N`. The other two boys ,whose ropes both make an angle `30^(@)` with the central rope, are pulling with forces of `50sqrt(3)N` and `100sqrt(3)N`. Find the magnitudes of the resultant pull on the trolltey.

Three boys are pulling a heavy trolley by means of 3 ropes. The boy in the middle is exerting a pull of 100 N . The other 2 boys, whose ropes both make an angle of 30^(@) with the centre rope, are pulling with forces of 50sqrt(3) N & 100sqrt(3)N . Find the magnitude of the resultant pull on the trolley.

3 boys are pulling a heavy trolley by means of 3 ropes. The boy in the middle is exerting a pull of 100 N . The other 2 boys, whose ropes both make an angle of 30^(@) with the centre rope, are pulling with forces of 50 sqrt(3)N & 100 sqrt(3)N . Find the magnitude of the resultant pull the trolley. Consider all the forces in the same plane.
