Document Summary
Phy1122 a discussion group february 25, 26 2015. Two identical small conducting spheres are separated by 0. 60 m. the spheres carry different amounts of charge and each sphere experiences an attractive electric force of 10. 8 n. the total charge on the two spheres is 24 c. The positive charge on one of the spheres, in c, is closest to: 12, 18, 24, 30, 35. The two spheres are connected by a slender conducting wire, which is then removed. The electric force on each sphere is closest to: zero, 3. 6 n, attractive, 5. 4 n, attractive, 3. 6 n, repulsive, 5. 4 n, repulsive. A small 80 g insulating sphere is suspended from point p by a silk thread that is. The sphere bears an unknown electric charge q. A positive point charge q = +2. 0 c is brought to a position directly below p, and the sphere is repelled to a new position, 30 cm to the right of q, as shown.
