Thnx a lot!

Hello, i hope i posted this in the correct section.. I have a question: the potential energy of a body when it is at point P a distance x from a reference point O is given by V = kx^2, where k is a constant. what is the force acting on the body when it is at P? the correct ans is 2kx in...

i did tht b4 i posted the qns. Tht;s where i got stuck cos the numbers were absurdly big and unfriendly, but its ok, I figured another way of doing already. thnx for ur help anyway!

Hi, I desperately need help with this qns: In an Argan Diagram, the points A, B, C, D represent the copmlex numbers a,b,c,d respectively. Guiven that ABCD is a rectangle describd in an anticlocwise sense, with AB=2CB, and a=-2-i, c=3+5i, find b and d (AB and CD are not parallel to the xaxis)...

nono, but AB doesn't have to be horizontal (i.e. parallel to the x axis) the rectangle can and probably would be slanted. the condition given is AB=2CD. if AB and CD are parallel to the xaxis the condition is not satisfied

I have! I've drawn the diagramme but i carn solve it and neither can my dad. I;m sorry, can u help me please? I;m doing Alvl pure maths (not further) by the way. thnx!
