An electron is released from rest at a distance of 0.490 m from a large insulating sheet of charge that has uniform surface charge density 3.70×10−12 C/ m 2 .
1-How much work is done on the electron by the electric field of the sheet as the electron moves from its initial position to a point 7.00×10−2 m from the sheet? W=
Express your answer to three significant figures and include the appropriate units.
2-What is the speed of the electron when it is 7.00×10−2 m from the sheet? V=
Express your answer to three significant figures and include the appropriate units.
1) work done on elelctron can be calcuate using below formula
2)speed of elelctron can be calcualate using below formula
1) work done on the elelctron, (3 significant figures)
2) Speed of electron, (3 significant figures)
