Alright, I know there are some smart fckers on here. I need yea guys to lend me a hand here. I have some stupid physics assignment due this evening, but I havent bought the book yet and Im stumped on the last two problems. I think i can get one of them, but here is the other.

Two equally charged particles, held 3.1 10-3 m apart, are released from rest. The initial acceleration of the first particle is observed to be 8.0 m/s2 and that of the second to be 10.0 m/s2. The mass of the first particle is 6.3 10-7 kg.

(a) What is the mass of the second particle? (in kg)

(b) What is the magnitude of the charge of each particle? ( in C )


Thanks in advance,
