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_Acos60^@+N_Bcos30^@=Mg`
and `N_Asin60^@=N_Bsin30^@`
On solving `N_B=sqrt3N_A`,`N_A=(Mg)/(2)`
