A block is projected with an initial velocity v_("Block") on a long conveyor belt moving with velocity v_("Block") (at that instant)having constant acceleration a_("Belt"). Mark the correct option regarding friction after long time (friction coefficient between block and belt = mu). If : {:(,"Column-1",,"Column-2"),("(A)",v_("Block")=2v_("Belt")and a_("Belt")=0,"(P)","zero"),("(B)",v_("block")=2v_("Belt")and a_("Belt")gt mug,"(Q)",f_(s)"static friction" (0 lt f_(s) lt f_(L))),("(C)",v_("Block")=2v_("Belt")and a_("Belt")=mug,"(R)",f_(L)"limiting friction"),("(D)",v_("Block")=2v_("Belt")and a_("Belt")lt mug,"(S)",f_(K) "kinetic friction"):} |
