Angle in Radian Conversion – Rankers Physics

Units: Practice Problem & Solution

The angle \(1'\) (minute of arc) in radian is nearly equal to, [2020- Covid]
\(4.85 \times 10^{-4}\text{ rad}\)
\(4.80 \times 10^{-6}\text{ rad}\)
\(1.75 \times 10^{-2}\text{ rad}\)
\(2.91 \times 10^{-4}\text{ rad}\)

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Units. Understanding the underlying formula is key to arriving at the correct answer below:

Convert \(1'\) to degrees, then to radians. \(1' = (1/60)^\circ = (1/60) \times (\pi/180)\text{ rad} \approx 2.91 \times 10^{-4}\text{ rad}\)

1. In an experiment four quantities (a, b, c) and (d) are measured with percentage error 1%, 2%, 3% and 4% respectively. Quantity (P) is calculated as follows \(P = \frac{a^3 b^2}{cd}\). \(\text{%}\) error in (P) is: [2013]
2. Assertion (A): The error in measurement of radius of the sphere is 0.3%. The permissible error in its surface area is 1.2%. Reason (R): Area of sphere, \(A = 4\pi r^2 \Rightarrow \frac{\Delta A}{A} = 4\frac{\Delta r}{r}\).  
3. Assertion (A): Mean absolute error of a measurement is always positive. Reason (R): Mean absolute error is defined as the magnitude of difference between true value and measured value.
