Question 86

The forces F1 F_1\,F1​ and F2 F_2\,F2​ are 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. Given that p=−19/10p = -19/10p=−19/10 and q=8/5q = 8/5q=8/5 find the resultant of the two forces.

Find the resultant of the two forces.
