**1. The problem statement, all variables and given/known data**

(Q)A 20 cm long capillary tube is dipped in water.The water rises up to 8 cm . If the entire arrangement is put in a freely falling elevator, the length of water column in the capillary tube will be

<a>8 cm <b>6 cm <c>10 cm <d>20 cm

**2. Relevant equations**

**3. The attempt at a solution**

From the elevator frame, the fluid will be weightless and only force on the "fluid in capillary's" upper part will be S[2(pie)r]cosA upwards{where A is the contact angle}

It will make the fluid rise and rise and reach 20 cm.

I want to ask will the fluid then overflow or will remain at the 20 cm mark.

I think It will overflow as the accleration will be upwards and even if the acceleration vanishes, due to velocity gained by fluid,it should overflow.

What you think oO
