my question is:
A stone of weight 32N is attached to a wire and hung from a rigid support. A string is then attached to a stone and pulled sideways with a horizontal force P until the tension in the wire is 44 N:
-what is the angle between the wire and the vertical?
-calculate the size of the force P
-repeat the calcuklation fro the case when the tension reaches 140N.

I found the answer for these question however, then i understood tht i might have to convert the weight 32N into kg before doing the question... so is my prediction right... or do i do the calculation with the 32N? if i am converting thn how do i convert 32N into Kg?
any valid answer will be welcomed. Thx in advance.

why shud i convert the tension into kgf. isn't tension the force and therefore shudn't it be kept the same...which is 44N

if you convert 32N to kg you should convert 44N to kgf and also the result(P) unit is kgf.
to solve the problem you may balance vertical and horizontal forces applied to the stone.
vertical balance:
32=44 cos A
where A is the angle between the wire and the vertical
horizontal balance:
P=44 sin A
