Answer:

shirt is little attached to the body, it can come off and fly away

Explanation:

In electrostatics, charges of different signs attract and charges of the same sign repel.

In this case, when a negative charge is placed on it, both the inventor and the shirt are charged, therefore there is a repulsive force, also there is an attraction between the positive charge of the roof attracts the negative charge, such as the shirt. of weak the two forces not greater than the resistance of the walk.

As the shirt is little attached to the body, it can come off and fly away

Two coins, made of different material, are placed next to each other so that they are touching. Both coins are 15mm in diameter.
nekit [7.7K]

The mass of the second coin for the given gravitation force is 20.9 g.

The given parameters;

  • <em>distance between the two coins, r = 15 mm = 0.015 m</em>
  • <em>mass of one coin, m₁ = 6.5 g = 0.0065 kg</em>
  • <em>gravitational force between the coins =  4.03 × 10⁻¹¹ N</em>

The mass of the second coin is determined by applying Newton's law of universal gravitation as shown below;

F = \frac{Gm_1 m_2 }{R^2} \\\\m_2 = \frac{FR^2}{Gm_1} \\\\m_2 = \frac{(4.03 \times 10^{-11}) \times (0.015)^2}{(6.67 \times 10^{-11}) \times (0.0065)} \\\\m_2 = 0.0209 \ kg\\\\m_2 = 20.9 \ g

Thus, the mass of the second coin for the given gravitation force is 20.9 g.
