Question 183

Three forces act on an object F1=−3i+5j+2k\mathbf{F}_1 = -3\mathbf{i} + 5\mathbf{j} + 2\mathbf{k}F1​=−3i+5j+2k, F2=2i+4j−k\mathbf{F}_2 = 2\mathbf{i} + 4\mathbf{j} - \mathbf{k}F2​=2i+4j−k and the resultant force is 4i+3j+6k4\mathbf{i} + 3\mathbf{j} + 6\mathbf{k}4i+3j+6k

Find F3\mathbf{F}_3F3​.
