Which of the following statement is true [J & K CET 2006]

When the coordinate axes are translated the component of a vector in a plane changes
When the coordinate axes are rotated through some angle components of the vector change but the vector’s magnitude remains constant
Sum of \(\bar{a}\) and \(\stackrel{\rightharpoonup}{\boldsymbol{b}}\) is \(\vec{R}\). If the magnitude of \(\bar{a}\) alone is increased angle between \(\stackrel{\rightharpoonup}{\boldsymbol{b}}\) and \(\vec{R}\) decreases
The cross product of \(37\) and \(4 \hat{j}\) is 12

Answer

(B) When the coordinate axes are rotated through some angle components of the vector change but the vector’s magnitude remains constant
