Question

solve with values given

Refer to Interactive Solution 19.37 to review a method by which this problem can be solved. The electric field has a constant value of 2.5 x 103 V/m and is directed downward. The field is the same everywhere. The potential at a point P within this region is 156 V. Find the potential at the following points: (a) 9.7 x 10-3 m directly above P, (b) 4.6 x 10-3 m directly below P, (c) 4.3 x 10-3 m directly to the right of P.

(a) Number Units eVkgcmV?CFV/m Refer to Interactive Solution 19.37 to review a method by which this problem can be solved. The electric field has a constant value of 2.5 times 103 V/m and is directed downward. The field is the same everywhere. The potential at a point P within this region is 156 V. Find the potential at the following points: (a) 9.7 times 10-3 m directly above P, (b) 4.6 times 10-3 m directly below P, (c) 4.3 times 10-3 m directly to the right of P.

Explanation / Answer

a) V = 2.5E3*9.7E-3 + 156=180.25 V

b) V =2.5E3*-4.6E-3 + 156=144.5 V

c) no change in height so no change in potential

so 156 V
