A unifrom disc of radius `R`, is resting on a table on its rim. The coefficient of friction between disc and table is `mu` Fig. Now the disc is pulled with a force `F` as shown in the Fig. What is the maximum value of `F` for which the disc rolls without slipping ?

A

`F_(max)=3 muMg`

B

`F_(max)=muMg`

C

`F_(max)=5muMg`

D

`F_(max)=5 Mg`

Text Solution

Verified by Experts

The correct Answer is:
A
`fR=Ialpha`
`=(1/2MR^(2))a/R`
`:. F=F//3`
`f`=frictional force
`F`=pulling force
