A) 2.2 N
B) 2.75 N
C) 0
D) 3.47 N
Correct Answer: B
Solution :
Free body diagram of block is as shown in the figure. Let us make observations from the frame of the tank. For equilibrium of the block, \[V{{\rho }_{w}}(g+a)=T+mg+ma\] \[\Rightarrow \]\[\frac{m}{800}\times 1000\times (10+1)=T+m(10+1)\] \[\Rightarrow \]\[T=2.75\,N\] Hence, the correction option is [b].You need to login to perform this action.
