Explain how a vector canbe resolved into its rectangular components components in two dimension . |
|
Answer» SOLUTION :In a two dimensional Cartesian COORDINATE system the vector `vec(A) `is GIVEN by `vec(A) = A_(x) hat(i) + A_(y) hat(j)` If`vec(A) `makes an angle `theta`with x - axis, and `A_(x) and A_(y)`are the components of along x-axis and y-axis respectively , then as shown in figure. `A_(x) = A cos theta, A_(y) = A sin theta` Where 'A' is the magnitude (length) of the vector `vec(A), A = SQRT(A_(x)^(2) +A_(y)^(2))`
