The electric potential at a point (x, y, z) is given by V = – x 2 y – xz 3 + 4 The electric field 
at that point is
Text Solution
Verified by ExpertsThe correct answer is:
A
Eflectric field at a point is equal to the negative readient of he electrostatic potential at that point. potential gradient relates with wlectric field according to the following relation E = 
= – 
= 
= [ 
(2xy + z 3 ) + 
x 2 + 
3xz 2 ]
