7. In order to collect weather data on a remote island, you decide to send a weather balloon to the location. You attach a 1 C charged object to the balloon and plan to propel it to the island using electrostatic force. Given the balloon's size and the standard wind patterns en route, you will need to overcome an opposing air resistance of up to 100 N at any point on the balloon's journey. How much charge will you need to propel the 1 C balloon from your location to the island 750 km away, considering the opposing wind? Ignore the curvature of the earth. 8. A metal sphere as a charge of +2.3 x 10-C and lies 2 meters away from another metal sphere of unknown charge. If the attractive force present between the spheres is 0.05 N, what is the charge on the second sphere?
