Friction: Practice Problem & Solution

Short Solution (Best for NEET):

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

Calculate max friction \(f = \mu mg\). Compare with applied force (F). If (F > f), then (a = (F-f)/m). Here, (f = 0.5 \times 10 \times 10 = 50\text{ N}). So, (a = (100-50)/10 = 5\text{ m/s}^2).
