Question
If the potential in the region of space near the point (-2, 4, 6)m is V = 80 x2 + 60 y2 volt. Then components of electric field at that point are :-
Options
A.Ex = 0,Ey = 50 v/m, Ez = 100 v/m
B.Ex = 320 v/m, Ey = - 480 v/m, Ez = 0
C.Ex = 100 v/m, Ey = - 240v/m,Ez = 0
D.Ex = 160 v/m, Ey = 140v/m, Ez = 0
Solution
Ex = - 
= - 80 (2x)
= - 160 (-2) = 320
Ey = -
= - 60 (2y) = - 120 (4) = - 480
Ez = -
= 0
= - 80 (2x)= - 160 (-2) = 320
Ey = -
= - 60 (2y) = - 120 (4) = - 480Ez = -
= 0Create a free account to view solution
