Vector Questions

This page contains Vector questions for B.Sc. first year mechanics. You can also practice these questions if you are appearing for any after B.Sc. entrance exams(ex. IIT JAM) for pursuing M.Sc. Question 1 Define direction cosines of a vector. If  $l_1$, $m_1$, $n_1$ and $l_2$, $m_2$, $n_2$ are the direction cosines of two vectors show

Lorentz Transformation

Derivation of Lorentz transformation equations using orthogonal transformations Let us consider two uniformly moving frames of reference where origins coincides at $t=0$. let the source of light is fixed at unprimed frame of reference and emits a pulse of light. The observer fixed in the unprimed frame of reference will observe a spherical wave-front propagating
