Map A Aa Sapling Learning macmillan learning Two particles, one with charge -6.29 x 106 Cand one with charge 3.55 x 106 C, are 0.0884 meters apart. What is the magnitude of the force that one particle exerts on the other? Number 25.7 Two new particles, which have identical positive charge qu, are placed the same 0.0884 meters apart, and the force between them is measured to be the same as that between the original particles. What is q? Number 3.23 x 10 C Incorrect. Previous g Give Up & View Solution Try Again Next d Exit Explanation

Explanation / Answer

here,

1)

q1 = 6.29 * 10^-6 C

q2 = 3.55 * 10^-6 C

d = 0.0884 m

the magnitude of force between them , F = k * q1 * q2 /d^2

F = 9 * 10^9 * 6.29 * 10^-6 * 3.55 * 10^-6 /0.0884^2

F = 25.7 N

2)

let the charge on new particle be q

F = k * q^2 /d^2

25.716 = 9 * 10^9 * q^2 /0.0884^2

q = 1.4 * 10^-5 C

the charge on each particle is 1.4 * 10^-5 C
