Question:

Two stationary positive point charges, charge 1 of magnitude 3.10 nC and charge 2 of magnitude 1.95 nC , are separated by a distance of 51.0 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.

Part A

What is the speed vfinal of the electron when it is 10.0 cm from charge 1?

Initially, the potential energy is expressed as follows: 7 -(9.0x10)(3.9+1.65)x10 (1.60x10-9) 0.3 -266.4 10-19 The final potential energy is expressed as follows (9.0 x10,)(3.9x10)(1.60x10-19) . (9.0x109)(1.65x10-9)(1.60×10-19) PE,- 0.1 0.5 561.6x10-19 +47.52x 10-19 609.12x10-19 = 6.09 × 10-21 The conserving energy is expressed as follows: 9.11x10)(-6.0912x1)-2664x10-N y-2.664x10m/s
