Question

Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 2.00 nC , are separated by a distance of 42.0 cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

What is the speed *v*final of the electron when it is
10.0 cm from charge 1?

Answer #1

The electron will face a force of attraction towards both the charges but the stronger towards charge 1 as it has a larger magnitude of charge and it field will be thus stronger.

Electric potential due to a charge is given by: assuming that the potential is zero at infinity.

The potential at the point when electron is in the middle is :

The potential at the point when electron is 10 cm from charge 1 is :

Applying the Work-Energy theorem for the electron gives:

**The final speed of the electron when it is 10 cm
from the charge 1 is 6.5976*10 ^{6} m/s.**
