Q130 / 180 · NEET 2020 (Phase 2) · Physics

The angle of $1'$ (minute of arc) in radian is nearly equal to

Correct answer
A
$2.91 \times 10^{- 4} rad$
B
$4.85 \times 10^{- 4} rad$
C
$4.80 \times 10^{- 6} rad$
D
$1.75 \times 10^{- 2} rad$

Solution

First, convert one minute to a second, $1^{'} = (\frac{1}{60}) °$ and then convert it into radian, $\frac{1}{60} \times \frac{π}{180} rad$ , so we can say that in one minute there is, $2.91 \times 10^{- 4} rad$ .

Hence, the correct answer is option: 'A'.
