Question:
two objects p and q carry charges 3.00micro coulomb and 0.44 micro coulomb.what is the number of electrons transferred from p to q so that they acquire equal charges
Answer:
q1 = - 3.0 µc
q2 = - 0.44 µc
Let n electrons be transferred from A to B so that A and B carry same charge
Charge on A = Charge on B
-3.0 + ne = -0.44 – ne (µc)
2ne = 2.56 µc
As e = 1.6 * 10-19 C, we get n = 8 * 1012
