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 :

Options

A. `3//4`
B. `sqrt(3)`
C. `3//2`
D. `2//3`

Answer

C
