Question 61

Three forces act on an object F1=−3i+8j+5k\mathbf{F}_1 = -3\mathbf{i} + 8\mathbf{j} + 5\mathbf{k}F1​=−3i+8j+5k, F2=6i−4j−2k\mathbf{F}_2 = 6\mathbf{i} - 4\mathbf{j} - 2\mathbf{k}F2​=6i−4j−2k and F3=2i+j+4k\mathbf{F}_3 = 2\mathbf{i} + \mathbf{j} + 4\mathbf{k}F3​=2i+j+4k

Find the resultant force.
