If a large drop of radius

2 \mathrm{~cm}

is splitted into 8 identical small droplets. Find out work done in this process if surface tension of liquid is

\mathrm{T ~dyne}/ \mathrm{cm}

View answer and explanation

Correct option: D

16 \pi \mathrm{T}

ergs

Option D (

16 \pi \mathrm{T}

ergs) is correct because it is the work done calculated using the formula for the change in surface area when a large drop splits into smaller droplets.

The average mass that must be lifted by a hydraulic press is

80 \mathrm{~kg}

. If the radius of the larger piston is five times that of the smaller piston, what is the minimum force that must be applied? A small drop of oil spreads over water because A film of water is formed between two straight parallel wires of length

20 \mathrm{~cm}

with separation of

0.5 \mathrm{~cm}

. The work done to increase the separation by

0.1 \mathrm{~cm}

is: The velocity of water in a river is

15 \mathrm{~m} / \mathrm{s}

near the surface. If the river is

5 \mathrm{~m}

deep, find the shearing stress between the horizontal layers of water. The coefficient of viscosity of water

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
