Given two vectors (mathbf{A} = 3mathbf{i} + 2mathbf{j}) and (mathbf{B} = mathbf{i} + 4mathbf{j}), find the position vector (mathbf{R}) such that (mathbf{R} = 2mathbf{A} - mathbf{B}).

Question

Accepted Answer

Step:1 ：Firstly, find the vector (2mathbf{A} = 2(3mathbf{i} + 2mathbf{j}) = 6mathbf{i} + 4mathbf{j}).Step:2 ：Secondly, subtract (mathbf{B}) from (2mathbf{A}) to get (mathbf{R} = 2mathbf{A} - mathbf{B} = (6mathbf{i} + 4mathbf{j}) - (mathbf{i} + 4mathbf{j}) = 5mathbf{i}).
