String is massless and pulley is smooth in the adjoining figure total mass or left hand side of the pulley side of the pulley is \[{{m}_{1}}\] and on right hand side is \[{{m}_{2}}\] . Friction coefficient between block B and the wedge is \[\mu =\frac{1}{2}\] and \[\theta =30{}^\circ \] Select the  wrong answer

A. Block B will slide down if \[{{m}_{1}}={{m}_{2}}\]
B. Block B may remain stationary with respect to wedge, for suitable values of \[{{m}_{1}}\] and \[{{m}_{2}}\] with \[{{m}_{1}}>{{m}_{2}}\]
C. Block B cannot remain stationary with respect to wedge in any case
D. Block B will slide down if \[{{m}_{1}}>{{m}_{2}}\]
Answer» C. Block B cannot remain stationary with respect to wedge in any case
