Solved: Two point charges of 30 nC and -40 nC are held
Chapter , Problem 63(choose chapter or problem)
Two point charges of 30 nC and -40 nC are held fixed on an x axis, at the origin and at x = 72 cm, respectively. A particle with a charge of 42 f.J.,C is released from rest at x = 2S cm. If the initial acceleration of the particle has a magnitude of 100 km/s2, what is the particle's mass?
