The potential of a field is given by equation
v = x2– y2. The best representation of electric field with x and y axis is:-
(i) 
(ii)
A
Only (i) is correct
B
Only (ii) is correct
C
Both (i) and (ii) are incorrect
D
Both (i) & (ii) are correct
Answer
Both (i) & (ii) are correct
Explanation
Solution
Ex = –
(When x is +ve Ex is in – ve 
direction where as when x is –ve Ex is in +ve direction)
Ey = –
(when y is + ve Ey is in 
direction and when y is –ve Ey is in 
direction)
