NEET UG PHYSICS MCQ: MOTION IN PLANE

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 $\mathbf{a}$ and $\mathbf{b}$ is $\mathbf{R}$. If the magnitude of $\mathbf{a}$ alone is increased angle between $\mathbf{b}$ and $\mathbf{R}$ decreases.

The cross product of $3 \hat{\mathbf{i}}$ and $4 \hat{\mathbf{j}}$ is 12 .
