A wheel of grindstone has applied at its axle 2 cm in radius a constant tangential force of 600 N. Find the change in angular momentum acquired after 8 s and also the torque acting

Explanation

To solve the problem step by step, let's break it down into two parts: calculating the torque and then finding the change in angular momentum.

### Step 1: Calculate the Torque
The formula for torque (τ) is given by:
\[ \tau = R \times F \]
where:
...
