Physics Vector Diagram (Paper 2)

[diwash]

Has any one done the vector diagrams of past papers...
M/J 10 Paper 23...Qno 2 (C)
M/J 04...............Qno1 (b)
has any one done these Questions...if have done Please post here....

Thanks in advance.

What no one is done it..some one please help...

T1cosQ + T2cosQ = 7
n
T1sinQ = T2sinQ
this is cux v hv 2 balance da forces
so from eq 2 we ve T1 = T2sin50/sin35
puttin in eq 1 (T2sin50/sin35)cos35 = T2cos50 = 7
T2 = 4.04N
T1 = 4.04sin50/sin 30 = 5.39N
hope u get it
let me look at da other one!

u draw da diag accordingly!

 

[workinghard]

4 mj 04 u draw a parallelogram with sides representing 6N and 8N
1 cm 4 one Newtron
da diagnol ll be resultant
geddit or shd i drw?!

i know the calculation part ..just need help in drawing part..

 

[workinghard]

u draw 2 straight horiaontal lines eq in magnitude
n one normal line eq in mag 2 7N one!

Dont we have to concern the angle between the forces while drawing the vector traingle...

 

[workinghard]

in j04 yeah u ve 2
but in j 10 dere is no angle since v r balancing da forces or say 7N force !
