if the radius of the capillary tube is doubled, what changes will take place in the hieght of rise of liquid with capacity tube
1 answer:
Explanation:
The height of the rise of liquid with capillary tube is given by the formula as follows :
Where
r is radius
It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.
If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.

Answer:
Number of turns per unit length will be
Explanation:
We have given that strength of the magnetic field produced by the solenoid B = 7 T
Current in the solenoid i = 200 A
Let the number of turns per unit length is n
Magnetic field due to solenoid is given as here
is permeability of free space n is number of turns per unit length and i is current
So
