If the period `'T'` of a drop under surface tension `'s'` is given by `T = sqrt(d^(a) r^(b) S^(c))` where `d` is the density , `r` is the radius of the drop. If `a=1,c= -1` then the value of `b` is

Text Solution

Verified by Experts

The correct Answer is:
3

By dimensional analysis
`t = d^(a//2) r^(b//2) S^(c//2)`
Solving dimension wise `b = 3`
