Question

A small metal sphere, carrying a net charge of $q_1 = -2.80 \,\mu C$, is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of $q_2 = -7.20 \,\mu C$ and mass 1.50 g, is projected toward $q_1$. When the two spheres are 0.800 m apart, $q_2$ is moving toward $q_1$ with speed 22.0 m/s (Figure 1). Assume that the two spheres can be treated as point charges. You can ignore the force of gravity.

Step 1

The electric force between two point charges can be calculated using Coulomb's Law: \[ F = \frac{{k \cdot |q_1 \cdot q_2|}}{{r^2}} \] where F is the electric force, k is the electrostatic constant (9.0 x 10^9 N m^2/C^2), q1 and q2 are the charges of the two Show more…

A small metal sphere, carrying a net charge of 91 = -2.80 µC, is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of q2 = -7.20 μC and mass 1.50 g, is projected toward 91. When the two spheres are 0.800 m apart, 92 is moving toward q₁ with speed 22.0 m/s 91 ( Figure 1). Assume that the two spheres can be treated as point charges. You can ignore the force of gravity.
