Two equally charged particles, held `3.2xx10^(-3) m` apart, are released from rest. The initial acceleration of the first particle is observed to be `7.0 m//s^(2)` and that of the second to be `9.0 m//s^(2)`. If the mass of the first particle is `6.3xx10^(-7) kg`, what are (a) the mass of the second particle and (b) the magnitude of the charge of each particle ?

Explanation

(a) `4.2 xx 10^(-7) kg`, (b) `6.6 xx 10^(-11) C`
