Question

In any region, if electric field is define as
Ē =(i +2j+K) V/m, then the potential difference
between two points A(0, 0, 0) and B(2, 3, 4) in that
region, is
(1) 6V
(2) 12V
(3) 8V
(4) 9V

Answer 1

Answer:V= E.r

r = r2-r1= 2 i+3j+4k

potential= (i+2j+k) .(2i+3j+4k)= 2+6+4= 12 V

Answer 2

Concept Introduction: The electric field is the basic concept of Physics.

Given:

We have been Given: Electric Field is given as

$Ē = (i +2j+k)$

radius is

$r = 2i + 3j + 4k$

To Find:

We have to Find: The Potential difference.

Solution:

According to the problem, Potential Difference is given as

$V = Ē.r \\ V = 1 \times 2 + 3 \times 2 + 4 \times 1 \\ V = 2 + 6 + 4 = 12V$

Final Answer: The potential difference is

$12V$
