1. What is Radius of Spherical Body 2?

Radius of Spherical Body 2 is the radius of the second spherical body in a Van der Waals interaction system. It is calculated based on the Hamaker coefficient, Van der Waals force, distance between surfaces, and the radius of the first spherical body.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R2 = \frac{1}{\left(\frac{A}{F_{VWaals} \times 6 \times r^2}\right) - \frac{1}{R1}} \]

Where:

\( R2 \) — Radius of Spherical Body 2 (Meter)
\( A \) — Hamaker coefficient (Joule)
\( F_{VWaals} \) — Van der Waals force (Newton)
\( r \) — Distance between surfaces (Meter)
\( R1 \) — Radius of Spherical Body 1 (Meter)

Explanation: This formula calculates the radius of the second spherical body based on the Van der Waals interaction parameters between two spherical bodies.

3. Importance of Calculation

Details: Calculating the radius of spherical body 2 is important in understanding and predicting Van der Waals interactions between nanoparticles, colloidal particles, and other microscopic spherical bodies in various scientific and engineering applications.

4. Using the Calculator

Tips: Enter all values in appropriate units. Hamaker coefficient in Joules, Van der Waals force in Newtons, distances and radii in Meters. All values must be positive numbers.
