The electric potential V at any point (x,y,z) all in meters in space is given by V = 4x² volt. The electric field at the point (1,0,2) in V/m is
Options
(a) 8 along positive X-axis
(b) 16 along negative X-axis
(c) 16 along positive X-axis
(d) 8 along negative X-axis
Correct Answer:
8 along negative X-axis
Explanation:
E⃗ = – [dv/ dx i + dv/ dy j + dv/ dz k]
= -8 x i V/m
E⃗(1,0,2) = -8i V/m
