A cylinder of mass M and radius R is resting on two corner edges A and B as shown in figure. The normal reaction at the edges A and B are: (Neglect friction)

A

`N_(A)=sqrt(2)N_(B)`

B

`N_(B)=sqrt(3)N_(A)`

C

`N_(A)=(Mg)/(2)`

D

`N_(B)=(2sqrt(3)Mg)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
B, C

For equilibrium `N_(A)cos60^(@)+N_(B)cos30^(@)=Mg`
and `N_(a)sin60^(@)=N_(B)sin30^(@)`
On solving `N_(B)=sqrt(3)N_(A):N_(A)=(Mg)/(2)`
