Identical isolated conducting spheres A and B have the same excess charges and are separated by a distance that is large compared with their diameters (Fig. 22-20a). The electrostatic force acting on sphere B due to sphere A is vector FAB. Suppose now that a third identical sphere C, having an insulating handle and initially neutral, is touched first to sphere AWhat is the magnitude of the electrostatic force F' that now acts on sphere B?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
