O-4 points cu10 18 P017 Two particles, with identical positive charges and a separation of 2.45 x 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration ai whose magnitude is 4.40 x 103 Mis2, while particle 2 has an acceleration a whose magnitude is 9.30 x 103 m/s2. Particle 1 has a mass of 5.7o x 10 6 kg. (a) Find the charge on each particle. q1 (b) Find the mass of particle 2. Additional Materials

Explanation / Answer

a).F=ma

for particle 1

F = (5.7*10^-6)*(4.4*10^3)

F = 0.025 N

also F=kq1*q2/r^2

here q1=q2=q

0.025 =(9*10^9)*q^2/(2.45*10^-2)^2

q^2 = ((0.025)*(2.45*10^-2)^2)/(9*10^9)

q = sqrt(1.66736*10^-15)

a).q = 4.08*10^-8 C

b).F=ma

0.025 =(9.3*10^3)*m

m = 0.025/(9.3*10^3)

m = 2.69*10^-6 KG
