Question 18

Three forces act on an object F1=−6i+5j+2k\mathbf{F}_1 = -6\mathbf{i} + 5\mathbf{j} + 2\mathbf{k}F1​=−6i+5j+2k, F2=3i+4j−5k\mathbf{F}_2 = 3\mathbf{i} + 4\mathbf{j} - 5\mathbf{k}F2​=3i+4j−5k and F3=7i−2j+6k\mathbf{F}_3 = 7\mathbf{i} - 2\mathbf{j} + 6\mathbf{k}F3​=7i−2j+6k

Find the resultant force.
