If the time period t of a drop of liquid of density d, radius r, vibrating under surface tension s is given by the formula `t=sqrt((d^(a))r^(b)s^(c))` and if a=1 ,c=-1 then b is

If the time period t of the oscillation of a drop of liquid of density d, radius r, vibrating under surface tension s is given by the formula t=sqrt(r^(2b)s^(c)d^(a//2)) . It is observed that the time period is directly proportional to sqrt((d)/(s)) . The value of b should therefore be :
