Question 40

Three forces act on a crate: F1=10i−3j+2k\mathbf{F}_1 = 10\mathbf{i} - 3\mathbf{j} + 2\mathbf{k}F1​=10i−3j+2k, F2=−4i−6j+5k\mathbf{F}_2 = -4\mathbf{i} - 6\mathbf{j} + 5\mathbf{k}F2​=−4i−6j+5k and F3=−2i+12j−3k\mathbf{F}_3 = -2\mathbf{i} + 12\mathbf{j} - 3\mathbf{k}F3​=−2i+12j−3k.

Find the resultant force.
