HW1 Serway, Ph EXPLORE Two charged particles, 21 and 22, each carrying the elementary charge of 1.6 x 10 C, are a distance of 16.60 x 10 12 m apart (A) Find the force that Q1 exerts on Q2 separation of particles 23.44 x 10 12 m (B) Find the force that Q2 exerts on force 4.20 x 107 N 21 (C) If the distance between the charges is increased to 1.9 times their initial separation, how is the force between them changed? CONCEPTUALIZE Use the Active Figure to visualize the situation. The two charges are a f particles 23.44 10 Sep specified distance apart, exerting force 4.20 x 107 N forces on each other that are proportional to the product of their charges and inversely proportional Display in a New Window to the square of the distance between them. The direction of the force is along the line joining the particles. CATEGORIZE This is a pr oblem in applying Coulomb's law to calculate the electric force between two charges ANALYZE (A) Find the force that 21 exerts on 22.Explanation / Answer
a. Apply F = Kq1q2/r^2
F = 9e9 * 1.6e-19 *1.6e-19 /(16.6^2*10^-24)
F = 8.36 *10^-7 N force on q2
----------------------------------
b. Apply F = Kq1q2/r^2
F = 9e9 * 1.6e-19 *1.6e-19 /(16.6^2*10^-24)
F = 8.36 *10^-7 N force on q1
-----------------------------------------------
if r is iincreased, f decrases by (1/1.9^2) times
i.e F = 8.36e-7/(1.9*1.9)
F = 2.316 *10^-7 N
