Question 78

Three forces act on an object:

F1=−5i+7j+4k\mathbf{F}_1 = -5\mathbf{i} + 7\mathbf{j} + 4\mathbf{k}F1​=−5i+7j+4k, F2=4i+6j−2k\mathbf{F}_2 = 4\mathbf{i} + 6\mathbf{j} - 2\mathbf{k}F2​=4i+6j−2k, F3=3i−5j+3k\mathbf{F}_3 = 3\mathbf{i} - 5\mathbf{j} + 3\mathbf{k}F3​=3i−5j+3k

Find the resultant force.
