MCQ
In non – uniform circular motion, the resultant acceleration is given by –
  • A
    $a_R=\sqrt{a_t^2-\left(\frac{ V ^2}{r}\right)^2}$
  • $a_R=\sqrt{a_t^2+\left(\frac{ V ^2}{r}\right)^2}$
  • C
    $a_R=\sqrt{a_t^2-\left(\frac{r}{ v ^2}\right)^2}$
  • D
    $a_R=\sqrt{a_t^2+\left(\frac{r}{ V ^2}\right)^2}$

Answer

Correct option: B.
$a_R=\sqrt{a_t^2+\left(\frac{ V ^2}{r}\right)^2}$
$a_R=\sqrt{a_t^2+\left(\frac{ V ^2}{r}\right)^2}$
