The angle of \(1^{\prime}\) (minute of arc) in radian is nearly equal to
- A \(1.75 \times 10^{-2} \;rad\)
- B \(2.91 \times 10^{-4} \;rad\)
- C \(4.85 \times 10^{-4} \;rad\)
- D \(4.80 \times 10^{-6} \;rad\)
Answer & Solution
Correct Answer
(B) \(2.91 \times 10^{-4} \;rad\)
Step-by-step Solution
Detailed explanation
\(\theta=1^{\prime}=\left(\frac{1}{60}\right)^{\circ}=\left(\frac{1}{60}\right) \frac{\pi}{180}\) radian \(=2.91 \times 10^{-4}\) radian
