use a scale 100N=1cm. draw a line 12.2cm starting at the left hand pin on the bar parallel to the 1220N force, and a line 9.5 cm staring at the right hand pin parallel to th 950N force. Where these to lines meet draw a diangonal to the opposite corner of the paralllelogram. Timnes this length by 100 to get the force in N.
11a)Use aluminium or lead sheets between the source and a detector. Nothing is detected therefore an alpha emittor
b)Use the left hand rule. Deflected into paper
