Question 5

Two forces F1\mathbf{F}_1F1​ and F2\mathbf{F}_2F2​ act on a particle. Their resultant is parallel to i+j\mathbf{i} + \mathbf{j}i+j.

It is given that F1=(3i−2j)\mathbf{F}_1 = (3\mathbf{i} - 2\mathbf{j})F1​=(3i−2j) N and F2=(pi+2pj)\mathbf{F}_2 = (p\mathbf{i} + 2p\mathbf{j})F2​=(pi+2pj) N, where p p\,p is a positive constant.

Find the value of ppp.
