A uniform disc of radius R, is resting on a table on its rim. The coefficient of friction between the disc and table is mu (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?

Options

A $F\ge 2\mu Mg$
B $F\le 3\mu Mg$
C $F\ge 3\mu Mg$
D $F\le 2\mu Mg$

Correct answer

C. $F\ge 3\mu Mg$

Step-by-step solution

Correct Option is : (C)

F\ge 3\mu Mg
