Q. 28

# A uniform disc of radius R, is resting on a table on its rim. The coefficient of friction between disc and table is μ (Fig 7.12). Now the disc is pulled with a force F as shown in the figure. What is the maximum value of F for which the disc rolls without slipping?

Answer :

According to question, let

f = force of friction

F = applied force

a = acceleration produced

So,

Solving above equations

We get
