Question

Suppose a van de Graaff generator builds a negative static charge, and a grounded conductor is placed near enough to it so that a 7.0 mu C of negative charge arcs to the conductor. Calculate the number of electrons that are transferred.

Answer 1

# _electron = 4.375 10¹³ electrons

Step-by-step explanation:

In this exercise it is indicated that 7.1 μC is transferred, let's use a direct ratio or rule of three. If an electron has a charge of 1.6 10⁻¹⁹ C, how many electrons have a charge of 7.0 10⁻⁶ C

# _electron = 7.0 10⁻⁶ C (1 electron / 1.6 10⁻¹⁹ C)

# _electron = 4.375 10¹³ electrons
