if the man can move with maximum acceleration a_(1)and a_(2) relative

1.	if the man can move with maximum acceleration a_(1)and a_(2) relative to the trolley car in forward and backward directions, respectively then :
Answer» `mu_(s)= (a _(1) +a _(2))/( 2G)` `mu_(s) = (sqrt(a_(1) a _(2)))/(G)` `mu_(s) =(a _(2) -a _(1))/(2g)` `a = (a_(2) -a_(1))/(2)` ANSWER :A::D
