c) Anidenticalmetalspherecarryinganegativechargeof1.0μCisplacednexttothefirstsphere. There is a gap of 10 cm between them. Calculate the electric force that each sphere exerts on
the other.

Answer 1

Answer:

Two tiny spheres have the same mass and carry charges of the same magnitude. The mass of each sphere is $$2.0 \times 10 ^ { - 6 } \mathrm { kg }$$ The gravitational force that each sphere exerts on the other is balanced by the electric force. (a) What algebraic signs can the charges have? (b) Determine the charge magnitude
