The angle of 1 ' (minute of arc) in radian is nearly equal to
Options
- A2 . 91 × 10 - 4   rad
- B4 . 85 × 10 - 4   rad
- C4 . 80 × 10 - 6   rad
- D1 . 75 × 10 - 2   rad
Correct answer
A. 2 . 91 × 10 - 4   rad
Step-by-step solution
First, convert one minute to a second, 1 ' = 1 60 ° and then convert it into radian, 1 60 × π 180   rad , so we can say that in one minute there is, 2 . 91 × 10 - 4   rad .
