Hi everybody.(adsbygoogle = window.adsbygoogle || []).push({});

I have started with the M1 Mechanics Course this term and my teacher gave me some exam questions to do over the half term break but now I am stuck on one of the questions and I hope someone here will be able to help me.

So here is the question:

(read l as lamda and m as mue)

A force F2 = (l i + m j ) acts on a particle.

Show that 2l - m + 1 = 0.

Given that the direction of F2 is parallel to j

I have started to think about this problem and came up with

(l + m) = (0+1) x constant

l = 0 x constant.

m = 1 x constant.

But this does not really help me at all. and i can't think about much else to do so I am very happy over every hint you can offer me.

Thanks in advance.

Ancient.
