If the velocity of a rotating body of mass 50 kg is given by

\vec V = 3\vec i + 4\vec j + 5\vec k

and rotating with radical vector

\overrightarrow r = 2\vec i + 3\vec j - 4\vec k

, then its angular momentum is

View answer and explanation

Correct option: D

50\left( {31\hat i + 2j - \hat k} \right)

Option D (

50\left( {31\hat i + 2j - \hat k} \right)

) is correct. Angular momentum is calculated as

\vec{L} = m(\vec{r} \times \vec{V})

.
