Question

Work done in moving an electron form one point to another in an electric field is 9.6×
10^−19 J. Find electric potential difference between the two points.​

Answer 1

By the end of this section, you will be able to:

   Define electric potential and electric potential energy.

   Describe the relationship between potential difference and electrical potential energy.

   Explain electron volt and its usage in submicroscopic process.

   Determine electric potential energy given potential difference and amount of charge.

Answer 2

$\ {\rm\green{A}\purple{N}\pink{S} \blue{W}\orange{E}\red{R☘}}$

Potential difference=V=−4−10=−14V

Charge=q=100e=−1.6×10^−17C

Now, potential difference, V=qW

⟹W=qV=−1.6×10^−17×(−14)

⟹W=2.24×10−16J
