The resultant of two forces F1 F_1\,F1​ and F2 F_2\,F2​ is (i−14j)(\mathbf{i} - 14\mathbf{j})(i−14j) N. Given that F1=(2pi−4qj)F_1 = (2p\mathbf{i} - 4q\mathbf{j})F1​=(2pi−4qj) N and F2=(3qi+4pj)F_2 = (3q\mathbf{i} + 4p\mathbf{j})F2​=(3qi+4pj) N find the values of p p\,p and qqq.

Find the values of p p\,p and qqq.
