हिन्दीA wheel of a bullock cart is rolling on a level road as shown in the figure below. If its linear speed is \( v \) in the direction shown, which one of the following options is correct (\( P \) and \( Q \) are any highest and lowest points on the wheel, respectively)?
Correct answer · Option 4
Point \( P \) moves faster than point \( Q \).
Explanation
For pure rolling, the linear speed of the top point \( P \) is \( v_P = v + v = 2v \), while the lowest point of contact \( Q \) has zero speed \( v_Q = v - v = 0 \). Thus, point \( P \) moves faster than point \( Q \).
