જો $\overrightarrow{r} = 3\widehat{i} + 4\widehat{j} + 6\widehat{k}$ અને $\overrightarrow{\omega} = -5\widehat{i} + 3\widehat{j} + 5\widehat{k}$ હોય,તો રેખીય વેગનું મૂલ્ય શું છે?

• A
  $2\widehat{i} - 45\widehat{j} + 29\widehat{k}$
• B
  $-2\widehat{i} + 45\widehat{j} - 29\widehat{k}$
• C
  $3\widehat{i} - 29\widehat{j} + 45\widehat{k}$
• D
  $5\widehat{i} - 6\widehat{j} + 4\widehat{k}$
