Question

af the following is true? Electric field is a vector and electric potential is a scalar O Electric field is a scalar and electric potential is a scalar. Electric field is a scalar and electric potential is a vector. Electric field is a vector and electric potential is a vector. (b) When calculating the electric potential due to multiple charges, I need to find the x and y components for each charge and add the components. O simply add the total electric potential due to each charge. (c) what is the electric potential at the point indicated with the dot in the figure below, in which q = 8 nC, x = 9 cm, and y = 12 cm? 288.75

Explanation / Answer

V = kq/r for charge q at a distance r from it

here are three charge with the point at 9 cm , 12 cm , 15 cm from them

so

V = kq/0.09 + kq/0.12 + kq/0.15

= kq(1/0.09 + 1/0.12 + 1/0.15)

V = 9*10^9*8*10^-9 ( 1/0.09 + 1/0.12 + 1/0.15 ) = 1880 Volts
