Text Solution

AI Generated Solution

To explain why the work done by a fielder when he takes a catch in a cricket match is negative, we can follow these steps: ### Step 1: Understand the Work Done Formula The work done (W) is calculated using the formula: \[ W = F \times d \times \cos(\theta) \] where: - \( W \) = work done - \( F \) = force applied ...
