A thundercloud has an electric charge of 43.2 C near the top of the cloud, -38.7 C near the bottom of the cloud and a distance betwee them of 1950 m. What is the Electric force between the 2 charges? Remember that Coulomb's constant (k) is equal to 8.99 *10^9 Remember F=(k*q1*q2) / r^2

(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?
