Answer» tion:12thPhysicsElectric Charges and FieldsProblems Based on Coulomb's LawTwo particles with identica...PHYSICSTwo particles with identical positive charges and a separation of 2.5×10 −2 m are released from rest. Immediately after their release, particle 1 has acceleration whose MAGNITUDE is 4×10 3 ms −2 . Particle 1 has a mass of 9×10 −6 kg. Then each of the particle has charge of : MEDIUMShareStudy laterVIDEO EXPLANATIONANSWERForce on particle 1 = mass X acceleration =9×10 −6 kg×4×10 3 ms −2 =0.036 NBy Coulomb's law, this force = 4πεo1 r 2 q 2 , where q is the charge on the particles and r is the distance between them (=2.5×10 −2 m).∴ 4πεo1 r 2 q 2 =0.036 N⇒9×10 9 × 2.5×10 −2 ×2.5×10 −2 q 2 =0.036 N⇒q=5×10 −8 Cmake me as brainliest |
