Explanation: The question asks which Railway station in India has the longest platform. Platform length depends on train traffic, station importance, and historical expansions. High-traffic junctions often build longer platforms to accommodate trains with more coaches. Considering records, media reports, and Indian Railways data can help identify stations known for long platforms.

Analogies like comparing faster and slower gears help understand the concept.

Explanation: To determine the angular speed, consider the minute hand completes 360° in 60 minutes. Converting minutes to seconds gives a small angular speed value in degrees per second. The principle of angular displacement over time applies here, allowing reasoning without giving the numerical answer. Visualization of a clock face can help estimate the rate.

Explanation: This question involves relative angular velocities about different points. The angular velocity about a point depends on the perpendicular distance from the point to the particle’s path. Using ω = v/R and comparing distances from the center C and point A helps reason through the ratio. This principle is applied in circular motion and Rotational Dynamics problems.
