VIDEO EXPLANATION

ANSWER

Given : r

1

=r h

1

=h r

2

=2r

Using rh=constant

∴ r

2

h

2

=r

1

h

1

(2r)h

2

=rh ⟹h

2

=

2

h

Mass of the water in the capillary M=ρ(πr

2

h) where ρ is the density of the water

Given : Mass of water that rises in the first capillary M

1

=5 g

∴ 5=ρπr

2

h ............(1)

Mass of water that will rise in second capillary M

2

=ρ(πr

2

2

h

2

)

M

2

=ρπ(2r)

2

2

h

=2×ρπr

2

h

⟹ M

2

=2×5=10 g
