Two equally charged particles are held 35 x 103 m apart and

Question

Compute all parts of given problem:

Problem: Two equally charged particles are held 3.5 x 10³ m apart and then released from rest. The initial acceleration of the first particle is observed to be 7.1 m/s² and that of the second to be 9.9 m/s². The mass of the first particle is 6.3 x 10⁷ kg.

Part A: What is the mass of the second particle?

Part B: What is the magnitude of the charge of each particle?

I need help to determine the magnitude of the charge of each particle.
