tube of certain diameter. This capillary
tube is replaced by a similar tube of
of 우
the diameter. Nowhater will
half
sise to
a height of​

Answer 1

Answer:

2h

Explanation:

Given,

Height in capillary h

1

Diameter of capillary d

1

We know that,

h×

r

1

[where r is the radius of capillary ]

Now the capillary is replaced by half the diameter.

i.e.

d

2

=

2

d

1

∴

h

2

h

1

=

r

2

r

1

=

2×d

2

d

×2

=2

⇒h

2

=2h

1

∴ the rise in the capillary is 2h.
