Answer:

[tex]Force = 0.0047175\ N[/tex]

Explanation:

Given

[tex]T = 0.075N/m[/tex] --- Surface Tension

[tex]r = 0.01m[/tex] --- Radius

Required

Determine the required force

First, we calculate the circumference (C) of the circular plate

[tex]C= 2\pi r[/tex]

[tex]C= 2 * \frac{22}{7} * 0.01m[/tex]

[tex]C= \frac{2 * 22 * 0.01}{7}m[/tex]

[tex]C= \frac{0.44}{7}m[/tex]

[tex]C= 0.0629 m[/tex]

The applied force is then calculated using;

[tex]Force = C * T[/tex]

[tex]Force = 0.0629m * 0.075N/m[/tex]

[tex]Force = 0.0047175\ N[/tex]
