Question 185

Three forces act on an object. F1=−6i+5j+3k\mathbf{F}_1 = -6\mathbf{i} + 5\mathbf{j} + 3\mathbf{k}F1​=−6i+5j+3k, F2=3i+4j−k\mathbf{F}_2 = 3\mathbf{i} + 4\mathbf{j} - \mathbf{k}F2​=3i+4j−k and the resultant force is 2i+6j+4k2\mathbf{i} + 6\mathbf{j} + 4\mathbf{k}2i+6j+4k

Find F3\mathbf{F}_3F3​.
