Expert Solution
Step 1: The electric potential

Given,

The work done by the field on the electron, increment W equals negative 5.21 cross times 10 to the power of negative 19 end exponent J

a. The electric potential, 

V subscript B minus V subscript A equals fraction numerator increment W over denominator q subscript e end fraction V subscript B minus V subscript A equals fraction numerator negative 5.21 cross times 10 to the power of negative 19 end exponent over denominator negative 1.6 cross times 10 to the power of negative 19 end exponent end fraction V subscript B minus V subscript A equals 3.25 space V

The points B and C are on the same equipotential surface,

V subscript C equals V subscript B
