MCQ
Two long parallel glass plates has water between them. Contact angle between glass and water is zero. If separation between the plates is $'d'$ ( $d$ is small). Surface tension of water is $'T'$ . Atmospheric pressure = $P_0$ . Then pressure inside water just below the air water interface is
- A${P_0} + \frac{{2T}}{d}$
- B${P_0} + \frac{{2T}}{{\left( {d/2} \right)}}$
- C${P_0} + \frac{{8T}}{d}$
- ✓${P_0} - \frac{{2T}}{d}$
