With what minimum velocity should a block of mass $m$ be projected from the left end $A$ towards end $B$ such that it reaches the other end $B$ of a conveyor belt of length $L$ moving with a constant velocity $v$ in the opposite direction? The friction coefficient between the block and the belt is $\mu$.
- A$\sqrt{\mu gL}$
- B$\sqrt{3 \mu gL}$
- C$\sqrt{2 \mu gL}$
- D$2 \sqrt{\mu gL}$
