Question
LAST NAME Man none 1. The electrical force of attraction between two small spheres that are 1.0 meter apart is F. If the distance between the spheres is decreased to 0.5 meters, the electrical force will then be (a) F/2 (b) 2F (c) 3F (d) 4F 2. If the charge on one of two small charged spheres is doubled while the distance between them remains the same, the electrical force between them will be (a) halved (b) doubled (c) quadrupled (d) unchanged 3. How many excess electrons are contained in a charge of -8.0x 101 coulomb? (b) 2 (c) 8 (d) 4Explanation / Answer
1) F = k/r^2
F = k/1^2
k = 1F for our purposes
Fnew = F/(.5)^2
Fnew = F/.25 = 4F
2) If the charge on one of the particles is doubled, the force is (doubled)
