Question 78

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

Find the resultant force.
