Two equally charged spheres of mass 1.0 g are placed 2.0 cm apart.When released,they begin to accelerate at 414 m/s².What is the magnitude of the charge on each sphere?

Question

Quizplus · Accepted Answer

The force between the spheres is given by F = ma = 1.0 g * 414 m/s² = 0.414 N. Using Coulomb's law, F = k * q² / r², where k = 8.99 x 10^9 N m²/C² and r = 0.02 m. Solving for q gives q ≈ 140 nC.
