An iron sphere weighing `10N` rests in a `V` shaped smooth trough whose sides form an angle of `60^(@)` as shown in the Then the reaction forces are
.
A. `R_(A)=10N and R_(B)=0` in case (i)
B. `R_(A)=10 N and R_(3)=10N` in case (ii)
C. `R_(A)=(20)/(sqrt(3))N and R_(B) ~= (10)/(sqrt(3))N` in case (iii)
D. `R_(A)=10 N and R_(B)=10N` in all the three cases
