Answer 1

Answer #1

Here ,

a) as the force on each of the masses is same

m1 * a1 = m2 * a2

8.2 *10^-7 * 9 = m * 7.8

m = 9.46 *10^-7 Kg

the mass of the second particle is 9.46 *10^-7 Kg

b) let the magnitude of charge of each particle is q

k * q^2/d^2 = m1 * a1

9 *10^9 * q^2/(4.4 *10^-3)^2 = 8.2 *10^-7 * 9

solving for q

q = 1.26 *10^-10 C

the charge q is 1.26 *10^-10 C
